All You Need to Know About The 3 Motorhome Classes

PublishedJune 30, 2020

Isn't it a bummer that learning about motorhome classes isn't easier??

(Thank you, long ago anonymous person that decided to name an RV type by using the ABC's. Eye roll.)

B & Ks Newmar Class A

Class A Motorhome

There's just no easy way to remember which is which. (It wasn't for me, anyway.)

If you come up with some easy way for people to remember which is which, PLEASE tell us in the comments section below!

The Three Motorhome Classes

Anyway, here's the deal. There are three classes of motorhomes in existence:

  • Class A
  • Class B
  • Class C

The categorizing into a 'class' ONLY applies to an RV with an engine in it. Therefore, RV classes only apply to motorhomes.

(Yes, there are 'sub' categories now, the 'B+' and the 'Super C'.)

None of the other classes of RV specify the actual type by 'class.'

The other types are called just what they are. A travel trailer is called a travel trailer. A fifth wheel is a called fifth wheel, etc. They aren't categorized by 'class'.

Only MOTORHOMES are classified.

Differences between the three motorhome classes include external appearances, and chassis differences. Some are also considered a van, maneuverability, cargo capacities, and more. Let's figure out which is which and teach you a thing or two!

Don't forget rule number one: ONLY motorhomes fall into these class categories. Pull-behind RVs do not.

The only types of RV that are 'classified' are motorhomes- RVs that you can drive.

If an RV is 'classified' or has a 'class,' it's an RV with a built-in engine.

Again, there are ONLY three RV motorhome classes. A, B, and C.

Now, let's go over the differences.

Identify Motorhome Classes By Shape

Let's talk about what the different classes of motorhomes look like because visually, the SHAPE IS how you can most easily identify an individual motorhome's class.

Sure, the structural bits about each define the types.

But first, let's simplify it by identifying a class upon looks alone.

Let's objectify these suckers!

  • A= Big rectangle on wheels
  • B= A van
  • C= Motorhome with a sleeping space that extends over the driver cab

The Class A Motorhome - 'Box On Wheels'

The unforgettable TV show Breaking Bad... that was a Class A motorhome. Hank used it as a rolling meth lab at the beginning of the unforgettable binge-worthy series. (Fun fact- in season 3, Hank calls the RV a Class C, which is incorrect.)

It was an old one, yes, and it had a sloping windshield instead of the more popular/identifiable vertical type.

Regardless, it was a box on wheels.

Also, the movie RV with Robin Williams. That was a Class A as well but with the more common flat/vertical front.

Even Cousin Eddie's RV in the classic movie 'Christmas Vacation'- that was also a Class A, albeit a very unique looking one!

Class A RV

These Three Famous RVs Were Versions Of a Class A Like This One

The Class A motorhome is likely what you picture when you think 'RV'.

They are the least aerodynamic thing invented for travel, possibly ever. These vehicles range from 25-45' long, with little to no aerodynamic shape about them. 

These units start as a bare chassis. Usually, they are either made from Ford (Gas engines) or Freightliner (Diesel engines). Then the RV companies build the box and its contents on top.

Size can be an issue with these models (They're big). Trips can cost a lot due to the high cost of the RV itself, larger/more expensive campground spots, and fuel costs combined with poor gas mileage. Whether gas or diesel, Class A motorhomes have the worst fuel economy.

Class A motorhomes are the largest and most expensive RVs of the bunch

Even so, some advantages are that they offer the most in luxuries for the best family vacation experience money can buy. (Thus the coined joke 'Class A-holes' for owners of class a RVs. No, Camp Addict doesn't believe that having a Class A means you're an a-hole, lol.)

Class A Amenities

The Class A motorhome comes equipped with everything from a master bedroom, living area, toilet, shower, full kitchen, and sometimes even two bath area toilets.

Space is often BIG in these monsters, and you may have up to 5 TVs in one unit. They can get as crazy as you can imagine, for that matter.

Larger ones almost always have at least one slide-out, which are notorious for becoming troublesome.

If you can imagine it, you can probably find it in the most decked out Class A RVs.

Class A Cost

The price tag for the Class A motorhome lifestyle is high as they are usually full of luxury and many comforts. Features can include interior conveniences as luxurious as a washing machine and dryer.

Class A motorhomes are typically huge, so they are challenging to maneuver. Because of their design and being built on a chassis, basement storage space is usually ample.

Class A Summary:

  • Largest of the three classes
  • Shaped like a box/rectangle
  • Often the priciest
  • Length: 28 to 45 feet +/-

Class B Motorhome

Scooby-Dooby-Doo!!! Yeah, the Mystery Machine was a Class B RV. It was a van.

The Mystery Machine should help you get the gist of what a Class B van looks like compared to the A or the C. Everyone knows what the Mystery Machine looks like!

Simply put, Class B motorhomes are vans made into an RV.

The Class B motorhome is usually far smaller than a Class A.

These vehicles are usually small, but not always. They range around 19-27 feet long.

Class B Van

Their variety can make a Class B motorhome a little tricky at times to identify. The basis of what makes a Class B a Class B is its chassis.

They either start their lives as:

  1. A shell of a complete cargo van, usually a Sprinter, Ram, or Ford Transit. (regular Class B motorhome, like the one pictured above.)
  2. OR, they (the Class B+) start as just the cutaway chassis of one of those vans. This means they start with the front end of the cab (driver area) with only the chassis attached. The 'butt' of the vehicle is open/empty. The RV manufacturer then builds that section on top of the chassis. (Class B+ motorhome)

These camper vans normally have all the accommodations necessary for a fun, complete camping trip.

What's a B+?

The newer termed 'B+' van is a motorhome that started life on a bare van chassis. Then the manufacturer builds the RV 'guts' on top of that chassis.

They are usually larger/broader than a traditional B because they can expand beyond being built inside the already built van cargo area.

TECHNICALLY, the B+ is a Class C camper but doesn't have the sleeping area over the cab traditionally found on a Class C.

Class B Amenities

Amenities usually include the normal household needs- a refrigerator, a sleeping space, sink, bathroom, appliances, a cooktop, and hookup capabilities for all the comforts a campground pedestal can provide such as power and water.

It may lack a permanent dining area due to the smaller size.

Class B motorhomes are the smallest, but they certainly aren't much (or any) cheaper than a Class A or C.

These campervans can journey just about anywhere. Travelers cross the country on roads quite easily in a class B van. A class B motorhome is sought after for these reasons.

They get you to new places with the comfort and setup you desire. The convenience of the smaller sizes of this RV is something that factors into a couples' pros and cons list for a new RV.

Class B Cost

Class B motorhomes are usually pretty compact, so they are better with fuel efficiency. However, they are still very pricey, so they are not for tiny budgets.

If you like to boondock, you are more nimble in a Class B than you are with a longer/larger RV. This is what I am looking for- a Class B cargo van and build out the inside myself.

Class B Summary:

  • A van that has been converted into an RV
  • Smallest of the classes
  • Best gas mileage
  • Usually pretty complete in amenities
  • Length: 19 to 22'

Class C Motorhome

I can't think of a single famous Class C. However, this is the typical type you see advertised as a rental.

There's a good reason for that. (Extra living space, easier to drive than a Class A.)

Class C Motorhome With a Cabover Sleeping Area 

Your Class C motorhome is USUALLY sized in between a B and an A. It's confusing, yes. As you can see, there's no logic in the letters that name them.

Class C Amenities

Expect to find all of the primary living necessities available in a Class C RV.

They sport a kitchen, usually a permanent dining area, closet space, decent cargo capacity, a refrigerator, likely with a freezer, bathroom, and often more than one bed.

The identifying exterior style of a Class C motorhome is TYPICALLY the sleeping/storage area over the driver cab.

BUT, what classifies an RV to be a Class C is that they build it on top of a van cutaway chassis.

This Is What Every Class C Starts Out Looking Like

Then the manufacturer builds the living quarters onto it.

Mileage varies per model, and with more beds, the advantage of these is easily sleeping smaller passengers. So families with children often go for these Class C RVs.

Class C motorhomes begin life as a bare van chassis

A 'Super C' build is on a heavier-duty truck cutaway chassis instead of a van cutaway chassis. (For example, a Ford 550 or a Freightliner chassis.)

Class C Cost

Class C motorhomes range anywhere between the cost of a B or an A and can vary wildly. It depends on how large you go and what level of comforts and luxury interior you want.

These are often smaller than Class A motorhomes and therefore fit easier into campgrounds.

The Class C is usually bigger than a Class B motorhome.

What's A Super C?

The Super C is a Class C RV that started off on not a van chassis, but on a medium-duty truck cutaway chassis. (Typically a Freightliner.)

Sometimes they are even on a heavy-duty truck chassis, their front end looking like that of a semi. They are bigger and longer than a regular C. We like to say that they are a Class C 'on steroids'.

Class C Summary:

  • Starts life as a van cutaway chassis
  • Often identified by the area over the cab
  • Sized in between most A's and B's
  • Price: still expensive but more affordable than most Class A's
  • Length: 24 to 36 feet +/-
  • Have a used motorhome you want to sell or curious what it would cost to buy a used RV? Find out what is my camper worth and see is you should buy or sell used.


Not always, but most of the time motorhome identification is made by looking at it.

Only motorhomes (RVs with engines built-in) are 'classed'.

Look At That Cabover Above The Driver Area! It's a Class C Motorhome.

  • Class A's are the largest and offer the most storage.
  • Class B's are vans. They are typically the smallest of the motorhomes, and are built inside a regular cargo van.
  • Class C's are built on a bare van chassis, and they usually have storage or a sleeping area over the driver's cab.
  • Class B+ is technically a Class C, but doesn't have the over cab sleeping area. B+ vans are built on a bare van chassis but are often larger than normal vans. 
  • Super C's are Class C vans built onto a medium or heavy-duty bare chassis such as Ford or Freightliner.

All three motorhome types can usually pull a tow vehicle. The amenities inside these adventure rigs include kitchens, bathrooms, living room areas, beds with a real mattress (RV king mattress are even available!), showers, and all the cabin necessities to make an RVer feel at home in their campers.

Identifying them is sometimes a little tricky, but with a little experience, they are mostly all identifiable by their shape and size.

I hope this helped you to understand the differences!

Once again, if you have a clever way for others to learn which is an A, B, or C, please sound off in the comments!

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.

  • Here’s a possible way to remember:
    Class A: If anything is “class A” that means the fanciest shmanciest or most luxurious.
    Class B: Behind the cab/driver (living/sleeping is all Behind the driver)
    Class C: Cab top – some of the RV is on top of the cab.

  • Thanks for putting together this great site! We’re looking for a Class C with bunk beds (based on our family size) and after reading through the manufacturer ratings, really like the Entegra Esteem 31f. We also like the idea of finding a rig that is 2-3 years old to get through the initial issues from the factory, but it looks like this is a newer model. Do you have any suggestions for something similar that we could find used from one of your recommended manufacturers?

    • Hey John,

      I like your thinking about getting a rig a couple/few years old!

      Entegra is definitely one of the best RV brands so worth looking at.

      I wouldn’t know about specific floor plans that are similar without spending a lot of time going through each manufacturer’s website/marketing materials. I just don’t currently have a spreadsheet (or the such) with all the floor plans on it.

      Yeah, that’s the ‘joy’ of shopping for a used rig. Floor plans come and go.

      Probably the best bet would be to go into the brochure archives for the RV manufacturers you are interested in and download prior year brochures to see if there is a floor plan that might work.

      Best of luck in your search for the ‘good enough’ rig!
