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?
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 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.
Spend the extra money for a quality 4-wheeled portable black water tank and you will be patting 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.
What About Thetford SmartTote?
No, we haven't included any Thetford portable grey water tanks or portable black water tanks in the below RV portable waste tank reviews.
The Thetford SmartTote has been around for years and was recently redesigned (and renamed the SmartTote2) fairly recently.
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 this unacceptable.
Therefore, we completely eliminated the Thetford SmartTote 2 from consideration.
Overall Best Portable Waste Tank
Barker 4-Wheel Tote-Along
These portable sewer tanks by Barker Manufacturing have a reputation for being incredibly durable.
They offer an ease of use that's made the ugly chore of dumping your camper waste tanks simpler.
25, 32.42 Gallon (choose size)
Continue Reading Barker 4-Wheel Tote-Along Portable Waste Tank Review
The Barker 4-Wheel Tote-Along portable waste tank is available in 16-gallon size (has hard rubber wheels instead of pneumatic wheels) as well as 25, 32 and 42-gallon sizes.
Speaking from experience, there is nothing more frustrating than using an RV sewer tote that has only two skinny wheels, which makes the 4-Wheel Barker Tote-Along worth its weight in gold.
2-wheeled sewer totes mean you have to lift up one end that is very heavy when it is full.
You then have to drag it along, with its skinny wheels digging into soft dirt or gravel.
Finally, you have to heave it into the vertical position to drain as 2-wheeled totes can't be drained in the horizontal position at a dump station.
The Barker 4-Wheel portable waste tanks solve all these problems.
Four wheels mean that it rolls along without you having to lift one end.
Four pneumatic (air-filled) wheels (16-gallon size has hard rubber wheels) on axles that have real wheel bearings (N/A 16-gallon size) means that gravel and other softer surfaces barely slows these portable black and gray water tanks down.
And the 3-inch dump valve (same as what your motorhome or travel trailer has) means the RV sewer tote only empties when you want it to.
There is seriously no better portable RV waste tanks for motorhomes or travel trailers on the market today.
Do yourself a favor and purchase a Barker Tote-Along.
It is the best RV portable waste tank you can buy.

Best 2-Wheel Portable RV Sewer Tote
Barker Original Tote-Along
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.
Choose Your Size
Continue Reading Barker Original Tote-Along Review
The Barker Original Tote-Along 2-wheeled sewer tote is available in 10, 15, 22 and 30-gallon capacities.
Just be aware that 2-wheeled RV waste totes are a pain to move.
Larger size capacity tanks can cause pain in your back since you have to bend down, grab the handle, lift up and tug it along.
And you have to raise the RV waste tote completely vertical to empty it at a dump station, which can be 'fun' when you have a full waste tank. (Not)
Why would you purchase the Barker Original Tote-Along (Blue Boy RV waste tank) instead of the much easier to handle and maneuver Barker 4-Wheel Tote-Along?
Because you only need to occasionally use a portable RV septic tank and don't want to spend the extra money on the 4-wheeled version.
If you are going to be using the portable RV dump tank on a fairly regular basis, go with the much easier to use Barker 4-Wheel Tote-Along.
You'll thank us later!

Best on a Budget Portable Waste Tank
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.
Continue Reading Tote-N-Store RV Portable Waste Tank Review
This portable RV waste tank is available in 18, 25 and 38-gallon capacities.
The 4-wheel Tote-N-Stor is by far a better option than a 2-wheeled RV tote tank.
This is because, with this tote, you don't have to lift one end to move it.
Also, it can be emptied into a dump station while in the horizontal position.
While the Tote-N-Store is less expensive than the Barker 4-Wheel Tote-Along, the Barker is an overall better choice.
Its superior wheels allow you to maneuver the portable waste tank on all types of surfaces.
Not just on hard, smooth roads.
There have been some consumer reviews indicating that the front wheels of the 4-wheel Tote-N-Stor portable RV septic tanks are not very durable and can come off.
These front wheels are just small diameter, hard rubber caster wheels that are suitable only for smooth hard surfaces.
It is easy to see that if you take this portable black water tank 'off-road' these small wheels may have issues.
Why would you purchase the 4-wheel Tote-N-Store over the Barker 4-Wheel Tote-Along?
If you are certain that you will only be using your portable RV tank on hard surfaces (concrete and/or asphalt) the Tote-N-Store is a cheaper option than the Barker 4-Wheel Tote-Along.
The Tote-N-Store is a MUCH better choice than a 2-wheeled tote (which you have to lift one end to move and dump).
But you need to be certain that you never need to take the camper sewer tank onto a soft surface.
If you do, go with the Barker and make your life easier.
Tote-N-Stor Portable RV Septic Tank
Tote-N-Store RV Portable Waste Tank Features and Specs:
- Available in the following (gallon) sizes: 18, 25, and 38
- Made from polypropylene
- Skinny, hard rubber wheels - very small diameter in the front which will make moving tote through gravel very difficult
- Translucent drain pipe acts as sight tube (when in stored position) so that you can tell how full the tank is getting as you are draining your gray and/or black tank into it
- Able to empty portable RV waste tank while in the horizontal position
- Comes with the following accessories: (1) 3" bayonet cap, (1) 3/4" cap, (1) 3 inch by 3- foot sewer hose, (2) 3" bayonet hose adapter, (2) 3" stainless steel hose clamps, (1) gray water hose
- Made in the United States
- 3-year warranty
- 18 Gallon Dimensions & Weight: 14.5" High x 27" Wide x 33.5" Long - 38 pounds
- 25 Gallon Dimensions & Weight: 14.5" High x 27" Wide x 41" Long - 40 pounds
- 38 Gallon Dimensions & Weight: 14.5" High x 26.5" Wide x 51" Long - 44 pounds
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 Usage Scenarios
If you are at, say, a state park campground that has no dump stationat all, you are going to 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.
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 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 will 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.

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.
Now you have everything you need for your arsenal against your black and grey tanks!

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.
