Portable RV Waste Tank Reviews

A RV portable sewer tank comes in either a 2 or 4-wheel version.

2-wheel versions only have the wheels in the back.

This means you get the 'pleasure' of lifting and supporting the front of a VERY heavy portable camper waste tank when moving it.

Oh, let's not forget that you get to stand it up on end while you dump out the contents at a dump site.

Did we mention a full portable black water tank is VERY heavy? It is- this is why 4-wheel portable rv waste tanks are superior. A 4-wheel portable RV waste tank rolls along without the need for you to hold it up.

When it comes time to dump, you leave the 4-wheel portable waste tank level with no need to heave it up vertical - a not so easy task with a large capacity tank that is full.

Why would one even consider a 2-wheeled RV portable waste tank? Dolla' bills, y'all!!

They sure are cheaper.

But, speaking from experience, the 2-wheel portable waste tanks are a huge pain (in the back) to use.

They are hard to drag across anything but a smooth surface.

So, go ahead and spend the extra money for a quality 4-wheeled portable black water tank and pat yourself on the back for years to come.

You won't miss the extra cash it takes to keep your body safe. 

So, here's the golden question:

Which one is the best portable sewer tank on the market? Below are the best RV portable waste tank reviews.

Here you can find out which RV tote tank is the best option for you.

Why No Thetford SmartTotes?

No, we haven't included any Thetford portable grey water tanks or portable black water tanks in the below RV portable waste tank reviews, and here's why.

The Thetford SmartTote has been around for years and was recently redesigned (and renamed the SmartTote2).

While the older version of the Thetford portable waste tank got good reviews (but is no longer available), the new version isn't doing so well.

There are an alarming number of complaints about the handle breaking after minimal use and other components failing prematurely.

Also, there are some serious design flaws that the below RV tote tanks don't suffer from.

We find all of these problems unacceptable.

Therefore, we completely eliminated the Thetford SmartTote 2 from consideration.

  • Less expensive than 4-wheel totes
  • Fairly lightweight
  • Built like a tank


  • Have to lift the front to move and dump
  • Skinny wheels best for hard surfaces

If you insist on purchasing a 2-wheeled portable sewer tote, then the Barker Original Tote-Along (aka Blue Boy) is your best bet.

Barker is known for their quality and durability, which is what you want when you are moving gray and black tank contents around.

Best on a Budget Portable Waste Tank

4-Wheel Tote-N-Stor

4 wheel tote-n-stor RV portable holding tank


  • Able to move and dump while horizontal
  • Storage compartment for accessories
  • Translucent tube to view fill status
  • Less expensive than our #1 choice


  • Reports of quality issues with front wheels
  • Skinny wheels best for hard surfaces

The 4-wheeled Tote-N-Stor is a good choice if you will ONLY be on hard surfaces.

Its small, narrow wheels mean that if you venture off of hard surfaces, the wheels will likely sink.

This makes it really difficult to move this RV sewer tank.

A Better Portable Septic Tank Hose

While all the reviewed RV sewer totes include a hose, the hoses are not of great quality.

Camco has an affordable, better option.  

It's their RhinoFLEX Tote Tank Sewer Hose.

This kit gives you a 3-foot collapsible high-quality hose with a clear 90-degree elbow that eliminates the hassles associated with the cheap hoses included with the portable septic tanks. 

See the below video for more information. (Video shows the older version with removable ends.)

Using A Portable RV Holding Tank

If you don't want the hassle of breaking your entire camp to dump your grey and black water tanks, you can get yourself a portable RV holding tank.

These RV waste totes are on wheels for ease of use, and you can attach them to the trailer hitch ball of your vehicle to (slowly) drive to the campground dump station.

Or, you can put it in the back of your truck to drive it to a dump station.

However, you can't drive 55 (or even 15) down the road pulling a portable black water tank behind you.

It's only made to tow very slowly. We're talking walking/jogging speed.

Otherwise, you will have to have the ability to put the portable black water tank in your vehicle.

Then, you must drive it to the nearest dump station.

As mentioned above, a portable RV waste tank is HEAVY when full. One gallon of water weighs around 8.3 lbs. 

Sewage will weigh a little more as it has solids in it as well.

Multiply that (water) by a fifteen-gallon tank (and that's a small RV tote tank) and that's about 124 lbs! Can you lift that?

You will only have to lift one end if it's on 2 wheels.

You can pull it behind you like a wagon without lifting an end if you get a portable waste tank with 4 wheels. portable waste tank with 4 wheels

Portable Waste Tank Usage Scenarios

If you are at, say, a state park campground that has no dump station at all, you have to pack everything up, hitch up if you have a travel trailer, and leave to get the job done. This is a lot of work.

Also, if you are boondocking somewhere, you could lose your spot while you are away dumping your tanks.

You can try leaving  your camping chairs and such at your site to 'claim' it. 

Still, that's a lot of hassle just to need to dump your RV portable waste tank.

This is where a portable black water tank saves the day.

With a portable black and gray water tank you eliminate the hassle of moving your entire house just to do this chore.

Your family can happily hang in the comfort of your rig while you go take care of it. It is much less of a hassle.

What you need to know is how large your rig's black and gray tanks are.

You may not want to get a portable waste tank for RV that is smaller than your rig's largest holding tank.

If you get larger, you can empty your black or gray tank partially or entirely without worrying about it overflowing when you are filling the portable waste tank. EEEEWWWW!!!

Additionally, when draining your black tank into your portable camper sewer tank you can use a little grey water flush after your black tank is empty to 'clean' the hose out.

Hey, gray water is still REALLY gross. But we'd argue that it's not as bad as sewage!

What Size Portable RV Waste Tank Do I Need?

If possible, buy a portable RV waste tank that will allow you to drain the entire contents of your gray or black tank into it.

For example, if your black tank has a 25-gallon capacity, purchase a portable black water tank that is greater than 25 gallons.

This allows you to empty a full black tank into your portable black water tank without fear of spilling.

You also need to consider the physical size of the portable waste tank since you are going to have to store it somewhere while not in use.

Dimensions and weights of the tote tanks can be found at the bottom of the "Continue Reading Review" section of each of the RV portable waste tank reviews.

Can't Lift 50+ Pounds? Problem SOLVED!

If you need to get your heavy full RV waste tank into the bed of your truck, and you aren't Arnold Schwarzenegger strong, a Rack Jack can help.

They come in three models. The Magnum model is capable of the heaviest loads while the 4x4 model is the lightest.

Easily pick up your portable generator, portable waste tank, or any other heavy object using this tool.

The Rack Jack 'plugs' into the hitch receiver of your truck (or SUV) and lets you easily load heavy objects into the back of your vehicle.

(We haven't used this product, but friends we have who have have all loved it. Neither of us have anything too heavy to lift to require this.)

Thoughts on 2-Wheeled Portable RV Sewer Tanks



Camp Addict Co-Founder

When I visit my parent's house I use their 2-wheel portable RV sewer tank to empty my trailer's grey and black tanks. I have to haul this RV sewer tote about 60 feet to their septic tank cleanout where I dump my waste.

This isn't a great distance, but it's a pain to do because I have to haul the RV waste tank across pea gravel. Did I mention that the tank only has 2 wheels? Yeah.

So I have to pick up the heavy (when full) front end and drag it as its tiny, hard wheels sink into the gravel. Ugh!

I'm not that old (I keep telling myself that), but I'm not 20 anymore either. Their portable black water tank is 25 gallons which means it weighs somewhere north of 200 pounds when full.

I have to heave the full tank into the vertical position to drain it. NOT. FUN.

My back never likes me after that kind of a dump session. 

The point of this story is the situation at my parent's place is ideal for a 4-wheeled portable holding tank so my back doesn't suffer.

Specifically the Barker 4-Wheel Tote-Along with its pneumatic tires would be an ideal fit for this type of terrain.

He-llllo. I'm the co-founder of Camp Addict, which my biz partner and I launched in 2017. I frigging love the RVing lifestyle but in December of 2020, I converted to part-time RV life. Heck, I lived in my travel trailer for over 5.5 years, STRICTLY boondocking for pretty much all of it. Boondocking is a GREAT way to live, but it's not easy. Anyway, I'm passionate about animals, can't stand campgrounds, I hardly ever cook, and I love a good dance party. Currently, I can be found plotting and scheming whether or not to start collecting farm animals (or plotting my next RV trip!) at my beautiful new 'ranch' named 'Hotel Kellyfornia', in Southern Arizona.

  • I noticed that the bottom of my 3” drain on my trailer is about 12.5” from the ground. What do I need to factor in for the height of the portable tank to make sure the black and grey water can drain into the portable tank? For example, one of the Totes I saw says the height is 11.5” tall – will I be able to effectively drain from my trailer’s tanks with that Tote or do I need a portable tank that is shorter? How much shorter? Thanks!

    • Hi Annie,

      Thanks for the comment and for checking out Camp Addict! Kelly and I appreciate it!

      I was recently checking out the portable tote options out there (Camco has a new one that looks promising), but the height is no shorter on the other options. 11.5″ is as low as I’m aware of.

      If you have 12.5″ clearance at the end of your 3-inch drain, you’ll be fine. Just as long as the tank is lower than the drain, it will work.

  • First time considering RV with no grey water tank, only black water. Is it OK to accumulate both grey and black water, and then dump from the one tank (black) when ready to clean out? Just wondering. All mine have had two tanks before considering just the one.

    • Hi Margaret,

      I don’t quite understand your question. I get that the RV you are looking at has no grey water tank, but where will you “accumulate both grey and black water”?

      If you intend to use the RV’s black tank to hold the grey tank as well, that is fine. But the RV would have to be plumbed to do this.

      I suspect that currently the RV just has a hose that is supposed to dump grey water on the ground? This isn’t the best setup as it severely limits where you can camp. Most places don’t want you dumping waste water on the ground.

      So you could drain that grey water directly into a portable waste tank, and then also put your black in there when you need to dump your black tank. But that would be a less than ideal setup. I’d think that would get very tiresome after a while.

      Given the choice, I’d go with a rig that was fully self-contained (has all the necessary holding tanks onboard).

    • Hey Lynda,

      Yep, because the Rhino products didn’t exist when this page was created. As I’ve mentioned in a below comment, I’ll be taking a look at the Rhino products when I get a chance (in the middle of a major website project right now) and if I had a crystal ball, I’d be pretty sure they’ll be making an appearance on this page.

  • There must have been a serious COVID19 backlog on production! could not locate the Barker models anywhere, So i got a Tote-N-Store, and returned it after opening the box I knew this was not for me. Mad search #2 and I ordered a Camco Rhino, opened the box and said YES! This one worked great, as in No Spillage, No Mess, well thought out! Don’t think I’d want to haul this more than a a hundred feet, but overall it’s a win. Based on the design and function it’s clear Camco wants in on all the poop business.

    • Hey Paul,

      The Camco definitely looks like a great poop hauler! I’ve definitely got it on my to-do list to check it out.

      Thanks for the firsthand report!

  • Hi there!

    I recently became a full time stationary RV dweller and am seriously confused about this holding tank situation.

    If my fresh water tank holds 25 gallons, and my grey water tank holds 25 gallons, and my black water tank holds 25 gallons…

    Why does my gauge say my grey water and black water tanks are both full?

    A full grey water tank plus a full black water tank should, combined, hold 50 gallons.

    Assuming I have used the entire 25 gallons of water my fresh water tank holds, where did the other 25 gallons of waste come from???

    It’s just little old me living in this rig and I certainly have not eliminated 25 gallons worth of feces and urine in only four days of living here. Plus, I “go” elsewhere more often than I use my trailer toilet.

    What is going on?

    I am a senior on a fixed income and it is going to cost $100 to have someone (Honey Bucket) come drain my tanks. I really want them to be full when the fellow comes to empty them. How can I be sure they are?

    • Hi there, Rebecka!

      So your sensors are telling you you’re full, eh?

      This is a SUPER common problem. It’s so common, in fact, that NOBODY I know relies on their sensors to know if they are full or not. You have to learn by experience.

      When your black tank is full, the toilet will start to back up, or won’t flush anymore. With my particular setup, I can see that the waste is coming up the vertical pipe that leads down to the tank. Many toilets have a bend in the pipe, so that’s not as good of an indicator. Though no matter your setup, you will eventually not be able to flush.

      As far as your grey tank goes, you will eventually have a drain that won’t drain anymore. It will start backing up.

      Yes, it may be unpleasant to do it this way, but it should only take once to be able to get a good idea of how long it takes you to fill each tank.

      Pro Tip: If you want to make your black tank go longer, don’t flush your TP. Place it in a lined wastebasket and dispose of it in the trash.

      Hopefully the honey bucket man can come the same day you call. ????

      I haven’t checked my black/grey sensors in years. Like, 4. ???? Been on the road for 5.

    Shame on you.

    • Hi Jim,

      Thanks for your comment- we are happy to clear up what it means for us to not accept payment from a company.

      We do not accept money from any manufacturer or seller for us to promote their products. Say brand X company came to us and said “Hey, promote our item Y, and we will pay you $xyz per month.” (Or any other type of reimbursement)

      We have never done that and we never will.

      We do use Amazon affiliate links, as we clearly state on every page that has them. We do not get paid to put those links on our site. We only get a small % IF someone uses the link and then buys.

      This costs the consumer nothing extra.

      They are also there for the benefit of the reader to easily find and get the products we recommend, should they choose to online purchase.

      So the products that we have chosen have nothing to do with someone swaying us to promote their product. We decide what is best, and that’s what we put on the site as our recommendations.

      We hope this clears things up for you.

    • I know these folks, and they are the most honest and thorough product reviewers out there with full transparency. However, there are many others out there that receive a product for free to “review” and they don’t disclose that. Watch for them, they are evil!

      • Thank you for your good faith in us, Paul! Even YOU disclosed that you know us, just as we disclose the fact that we don’t allow companies to ‘buy’ us in any way.

        Besides, what good is receiving some product for a mere tens or hundreds of dollars compared to the value in the trust of thousands of readers who come to our site for recommendations? The trust is our NUMBER ONE priority. It’s our reputation. No company’s free product is going to compensate us enough to make a living, lol!

        We have accepted products for review. This is always stated very clearly if we do go on to recommend it. But we never take compensation or allow companies to ‘convince’ us to recommend their product.

        Paul, thanks again for your continued support!

    • Dang Jim. You should do a better job understanding rather than shoot from the hip on things you don’t fully understand. Try better next time before spewing ugly accusations. Shame on YOU.

    • Hi Susan,

      What problem are you having with it as far as not being able to lift it?

      Can you be more specific? Which waste tank do you have? Do you have straps for it? Have you already tried to move it, and if you cannot, what’s the issue?

      More information will help us to help you out.

      Thanks, waiting for your reply.

    • I don’t know if you already have the Rack Jack, but another solution is a macerator pump. It grinds up any solids kind of like a disposal and pumps it through a hose to your portable waste tank. No need to take the waste tank out of the bed of your truck to empty your RV holding tanks.

      • Hi Billie Sue,

        Do you find that the macerator pump deals with the uphill flow from your RV to the portable waste tank in the bed of the truck with no problem?

        What do you do when it comes time to dump the waste tank into a dump station (or other appropriate sewer inlet)?

        • Due to the current campground restrictions, we are moving toward totally self contained/dispersed camping. Waste disposal is one of the issues we are planning for. We haven’t yet decided on the specific macerator pump we will purchase, but my research indicates that this is a viable approach. These pumps are rated for the distance and the amount of lift they can achieve, and having the waste tank in the bed of a pickup is pretty much what they are intended for. There is no reason to move the waste tank to empty it. It can be emptied in place using a standard waste hose. We’ve watched YouTube videos showing the entire procedure, and it seems reasonably painless. A macerator pump weighs very little and doesn’t take up much space which to me is an advantage over the hoist. I’m not saying that it is preferable for everyone; only that it is an option to consider.

          • Thanks for the further explanation, Billie Sue!

            I’m not sure macerator pumps are primarily intended for pumping into a portable waste tank in a truck bed, but that’s certainly one use case assuming the pump can handle that much ‘lift’.

            As far as dumping the waste tank while it’s still in the bed of your truck, that’s certainly possible. Just be careful, as messes have been known to happen if you aren’t super careful. And nobody wants this kind of mess in the bed of your truck. It’s also going to require a longer than normal sewer hose from the tank to the dump ‘port’, plus two people to make sure the hose stays in the ‘port’ as the waste tank is being drained.

            It sounds like you are thinking this through correctly.

            Of course the ultimate solution to this would be to have a rig with large enough holding tanks to get you through the time you can stay in one place on public lands (usually in the two weeks range). I can do this with my decently sized tanks, but it’s just me. Most rigs have inadequately sized holding tanks, unfortunately.

          • We’re happy with our trailer and don’t want to replace it. We have been happy with staying at state parks until covid-19. My husband and I are both very methodical. We’ll practice with a gray tank full of clean water until we are confident, and even then we won’t be careless. I think that this will work for us, and I presented it in your comment section because I thought it might be helpful for someone else.

  • We will have a porta-poddy outside for dry camping. But we are older and have to pee alot at night. Could we use the portable 4-wheel holding tank taken from our grey and black water, then wheel it over to the serviceable porta-poddy to dump it in there instead of taking it to a dump station miles away?

    • Hi Geri,

      We don’t see why not? Unless you are doing it so often as to cause the company to have to empty it more often than they normally would. That’s the only reasoning we can see that might make it be a negative thing.

      One thing to keep in mind is that the portable waste tank is going to become very heavy when filled with liquid. And you are going to have to lift it up in order to dump it into the porta-potti. This may make it extremely difficult, or impossible, to dump there.

  • Thanks for the candid observations and reviews of the noted portable waste tanks. My mouse was on the PURCHASE button to buy a Thetford SmartTote2, but i decided to peruse your sight about tanks in general and saw your notes on that model. Further checking (on Camping World site) of SmartTote2 reviews seemed to reflect the same conclusion. Thanks for all the good ‘poop’.

    • Hey Rick!

      We sure will! It’s on our to do list for early 2019. We wanted these new portable waste tanks to be on the market for a while before we took a look at them. The time is right to give them a look! We’ll update this page once we’ve had a chance to see what they are all about. Thanks for your patience and Camp On!

  • where were you 30 years ago when we first started full time RVing? Your awesome videos would have saved us hundreds of dollars, a bad back and countless WHOOPS at the dump station. Newbies should really pay attention. Thanks we’re buying yet another new portable tank and with your sage advice we’ll finally get it right. Got an opinion on the Camco Rhino tanks?

    • Thanks for the kind words, Roux! You just hit the nail on the head why Kelly and I wanted to create Camp Addict – because there was no comprehensive, one-stop shop for learning about RV products and accessories. Glad to hear that we are succeeding!

      The Camco Rhino Tote Tanks are relatively new to the market and didn’t exist when we created this page. They look very nice and we’ve been keeping an eye on them. Before we considered adding them to the page, we wanted to have them out there ‘in the wild’ for a bit so people could get experience using them.

      They do look like a very good option for a two-wheeled tote tank. Maybe even good enough to take the #1 two-wheeled waste tote position away from our current selection. I’ve got it on my list of things to look into (yeah, that list is growing by the day!).

      Having said that, they still are a two-wheeled tote, so they suffer from most of the negatives this style of portable waste tank has. Including needing to be lifted up at the front to haul around. Not as big of a deal if you are using the 15 gallon version, but with the larger versions, things get heavy quickly. But if you have your heart set on a two-wheeled tote, this looks like it may be a viable option.

      Thanks for the question and Camp On!

  • I have been RV’ng for several years and have a pretty good handle on the blk and gray waste tanks. But I found the wealth of information here extremely interesting, not because it reinforced most of the procedures I already do, but because it is very well written with a many ideas I haven’t thought of. I was searching for info on portable waste totes. I don’t see on any site suggestions for storing these totes while traveling. I wonder if there’s a way to secure one to the rear bumper on a TT? I would need the physical dimensions of a tote to figure this out but I don’t find those on any tote discription. Where would I find that information? Thanks for the detail in your site!

    • Hey Mo!

      Thanks for your kind words! Great to hear that even as a seasoned RVer you were able to take away something from this page.

      The dimensions (including weights) of each tank model and size can be found at the very end of each individual review – under the ‘Features and Specs’ section. Dimensions are the very last of the bullet points.

      You will need to expand each review by clicking/tapping on the bar (right below the ‘Buy on Amazon’ button) that starts with “Continue Reading…” Sorry for the confusion!

      I’ve seen a lot of people attach their portable waste tanks to the ladder on the back of their rig (assuming it has one). Obviously the bed of a pickup would be a great place. And for those of us (not me!) that are fortunate enough to have an abundance of cargo bays, you can always use one of those to store your portable waste tank. As far as I know, there is no purpose-built tank holder.

      Great question, Mo, and Camp On!

    • I cut handles and wheels off a cheap dolly from Harbor Freight. I mounted it to ear camper bumper with “U” bolts. Hold the tote in place with ratchet straps.

    • Hey James,

      Interesting question. My answer is, maybe. How’s that for being specific. ?

      In all seriousness, it’s going to depend on where you are. I’m not aware of any nationwide company that does this ‘dirty’ job. But there are definitely local companies, in certain locations, that do it. We’ve been involved in group boondocking events where a truck has been hired to come out and pump out whomever needed it. So these companies definitely exist. Again, it’s going to depend on where you are located.

      I’d do some poking around online, starting with a Google search. Maybe start with the search term “RV pump out service near me” and see if that yields any results.

      Good luck and Camp On!

  • Need help choosing brand of portable sewage tank. Mordvi read more confused I get. i travel alone so want to be able to handle alone

    • Hi Marcia,

      Sorry for the confusion. When it comes to portable black tanks you need to really consider two things – size and style.

      Style is whether it has only one set of tires or two. One set of tires means you have to physically lift the front of the tank to move it – not fun! Two sets means it rolls along by itself which requires less physical effort on your part.

      Size has two considerations – how big your holding tanks are (if you want to be able to completely dump your RV’s tank into the portable holding tank in one go) and how bulky the portable tank will be (which means you have to store it somewhere and you have to move it when it’s full). You might want to consider going with a smaller portable waste tank just to make it easier to handle. This may mean that you will have to be VERY careful when transferring waste from your RV to the portable tank so that the portable one doesn’t overfill.

      This is assuming you need a portable tank at all. If you move a lot, you can just dump your tanks frequently. But if you are stationary, without full sewer hookups, a portable tank may be what you need.

      Hope that helps. Camp On!

      • Hi, there’s more than just size and style! Consider the dimension of the wheels! Things to think about, will you be be towing in areas without paving? Non-paved areas require bigger wheels, maybe look for wheels that won’t go flat. Also consider if the small axel will come apart when towing the tank. Also consider whether you can see/tell how full the portable tank is getting? Do you really want to end up with extra blackwater in the tube? How easy is it to flush the tank after dumping. Does the portable tank easily store away or hang from your RV ladder?

        • Hey Denise,

          All GREAT information! (A lot of which is covered in the above portable holding tank guide and reviews.)

          Thanks for your valuable insight and happy dumping of your waste tanks using the portable method. 😉

  • I bought s smart tote . The connector to the trailer popped off twice while draining the gray water to the tote . Not sure I figured the gasket seals are installed correctly on The connector. It does not go on very tight .

    • Hi Dennis,

      Sorry to hear that you are having problems with your Thetford SmartTote. We actually do not recommend this brand because of the poor reputation it has. I suggest you contact Thetford to see how they can help.

      Best of luck and Camp On!

  • Quit reading at “WRONG TOILET PAPER” hard to trust your reviews when you’re wring right off the bat. There are tons of videos online that show toilet paper dissolve tests, and that it doesn’t matter which you use, that the real key to clean black tanks is plenty of WATER to dissolve everything and to flow out when dumping. “It” flows downhill as the old saying goes, but “it” needs water to flow in

    • Hi, longtime camper- thanks for your comment! Toilet paper can ABSOLUTELY contribute to tank clogging. It’s simply good measure to do everything possible to avoid a clog, as nobody in their right mind wants to have to deal with such a situation. Yes, using too little water can also contribute to tank clogging. It all adds up.

      Using a TP that dissolves better than others is just a smart preventative measure to take to keep your tanks flowing properly. I (Camp Addict Kelly) take measures one step further and I don’t put any TP down my tank. I can use whatever TP I want, and it makes me that much more confident that I will never have a clog.

      We’re sorry you don’t feel you can’t trust Camp Addict because of this, but we stand strong by our recommendation. We always happily re-review our recommendations when someone comments with a reasonable disagreement about something on Camp Addict. Why wouldn’t we? It only serves to help us stay updated and reliable.

      However, in this case, we are standing by our recommendation. Even if we WERE wrong about it, it wouldn’t hurt anything or anyone to use TP that dissolves easier than other brands.

      The brand that dissolved the best in the Fit RV’s video on our RV toilets page is a very common grocery store brand, Charmin Ultra Soft, which is easy to buy and is easy on the butt. No harm, no foul. We think it’s better to be safe than sorry.


    • Hi Paige! Yes, you can pull a portable black tank behind your vehicle by attaching it to the hitch. You can’t go very fast with it, obviously, but it’s one way to transport your, um, ‘bits’. Thanks for reading and Camp On!

  • Hello, I am very new at this! So…if I am using the portable waste tank, I leave the grey and black valves shut, until ready to empty into portable, correct? I do not leave valves open and it automatically/continously flows into portable tank….???

    • Hey girl! We were ALL “new to this” at one point, so join the club! You are correct- leave the valves shut. (SERIOUSLY, I just now typed “shut” with an I first, if you know what I mean… but had to correct it. Kinda funny. ?) You are correct though… leave the valves CLOSED, ALWAYS for the black tank. Only connect the portable tank when you are ready to empty, open the valve, and if your portable is smaller than your black or grey tank, you can LISTEN for when it’s getting full. You will get an ear for it. If you are connected to sewer, you can leave the grey open if you prefer. If you leave the black tank open, the solids drop down, and the liquids flow out, creating the infamous “poopciscle” that can clog your tank. Keep it up, the learning process is CONTINUOUS. I am blown away by how much there is to take in and know. : ) Thanks for checking us out, and have fun out there!

  • Thanks for the info. I’m gathering information and stuff getting ready to hit the boondocker road. I recently purchased a pop up for my camper and a 16×7 enclosed cargo trailer. I’m In the process of some upgrades and mods. Gonna be hauling Bud, my Harley, and the rest of my possessions. Also in the process of downsizing my belongings. Plan on living on the road full time. I’m 63 years young, single, and retired on SS. Been dreaming about doing this for years…
    Maybe I’ll cya down the road sometime

    • Wow, the cargo trailer route, very cool! They have many benefits that traditional RV’s do not. (Lightweight, not as much to seal, design how you wnat it, higher clearance sometimes, etc) CA Kelly has considered the cargo trailer route, too, but she’s not very handy. If I find one already remodeled that works perfectly for me- I’m on it! You are in for a ride, Ziggy! Have a ball, life is about to get very ‘real’. You could very well see us down the road. As long as you’re not full-time in campgrounds! ???? Camp On, Ziggy and thanks for the comment!
