What determines the Class? A, C, Super C, B, B+, confused

The only class differences clearly defined are A and C. A's are specially built around a specific chassis and the driving compartment is part of the house, no van front. Class C's have a cut away van chassis with a house built behind and sometimes over the cab.

Then came Class B which muddied the waters a bit. First a class B was a van body modified for RV accouterments inside. Then they expanded them and pushed out the sides but had no cabover. I even saw some that widened the van chassis. Then along came what was called B+. Generally it was a Class C with no cabover or an entertainment center as a cabover. Purists can't agree on whether they are a Class B or a Class C. I had a Winnebago Aspect which some called a Class B+ but I felt it was really a Class C.

The upshot of all this is what each is called is not important. I know this and other forums have threads differentiated by class but if you assign yourself to 1 you may be missing out on information in the other. The same goes for searching for one for sale, If you only search for a Class B, you might miss the perfect one that is listed as a Class C. Don't worry about what it is called, Find the one you like and go camping.

After you climb in and out of a 100 or so, you will be able to tell the Class at a glance. Enjoy shopping.

A fair amount of the class c coaches have the entertainment unit in the overhead therefore giving you more useable space elsewhere.

RVIA has defined three motorhome classes.

Type A is built on a bare chassis (but includes conversions of motorcoachs which might be a unit-body shell).

Type B is built on a complete van, although some manufacturers might remove some of the van walls.

Type C is built on a cab-chassis or cutaway (cab missing the back wall). SuperC is just a marketing term for a large C built on a chassis with conventional cab instead of cutaway. Most sold as B+ are Type C without a bed over the cab, but some marketers will call a widened B a B+, so you can't be sure what someone is talking about when they say B+.

This is what I've always heard and read.

As for changing from "class" to "type", I suspect that is to help reduce confusion with driver license classes.

OP - I wouldn't cross out Cs either. Some have an entertainment center instead of a bunk. And a bunk can be used for extra storage and/or grandkids, etc.

So I guess I should just look at the Class A and B+

I wouldn't rule out a C. You don't have to sleep up there but it can be re-purposed for light weight storage.

It's my understanding that a "B" is a van that has a modified interior to accommodate a bed, kit, bath....

A "B+" is an extended "B" and has a small storage space over the driver/pass area....

A "C" is a small truck cab and frame (think F350 or F450) that has a motor home built on the frame (where the truck bed usually went) and usually has a bed over the cab. It can come in a multitude of different lengths and always has a gas engine.

A "C+" is the same as a "C" but will have a diesel engine and a more heavy duty frame. Some even come on a large truck frame (like a Freightliner) and can be up to 40' long but will still have the cab of a truck .

An "A" is a complete motor home built on a truck type frame. The driver's area is part of the living room (both chairs can be rotated 180 degrees). It can be either a gas engine (up front) or diesel (in the rear) and can range from 28' to 45'.

Typically the $$ range will be from a low on a "B" to a high on an "A" with a "C" in the middle.

Hope this helps

According to the Recreational Vehicle Industry Association (RVIA), there are only three classifications, A, B, & C. A few years ago they changed the label from "Class" to "Type", apparently to be more politically correct.

What is a Recreation Vehicle (RV)?

Very helpful. Thanks.

Size has nothing to do with it:
- A: there is no van or pickup body parts visible. It comes to the RV manufacturer as just a frame and drivetrain (maybe a drivers seat) and the RV manufacturer builds the entire body. (Bus conversions also fall under A).
- B: The front is from a van (or occasionally pickup) but there is no bed over the front. There may be a small amount of storage in the overhead but much smaller.
- C: The front is from a van (or occasionally pickup) and there is a bed over the front.

B+, super C, etc...marketing terms that are undefined.
