Motorhome classes: A, B, B+, C and Super C
Compare motorhomes by construction and actual configuration: Class A is the integrated coach form, Class B is a camper van, and Class C has a living body behind a cab. B+ and Super C are market descriptions; verify the specific chassis, labels, dimensions and ratings before buying.
Cab shape does not settle capacity or crash protection
| Description | Verify on the actual motorhome |
|---|---|
| Class A | Chassis, cockpit restraints, entry, dimensions and service access |
| Class B | Conversion labels, travel seats, storage and exterior height |
| Class C or B+ | Cab/chassis specification, body width, travel seating and loaded axle weights |
| Super C | Truck chassis, combined rating, receiver and actual license requirements |
There is no universal two-VIN rule for motorhomes. 49 CFR 567.7 addresses alterations to an already certified vehicle: original certification labels remain and an alterer adds the specified label. A coach serial number is not automatically another VIN. Match the vehicle identity and applicable certification documents rather than inferring them from class.
A receiver rating is only one towing limit
The 2026 Winnebago Travato specification lists 12,000 lb GCWR, 9,350 lb GVWR and a 3,500-lb drawbar rating with 350-lb maximum vertical tongue weight. At an assumed actual loaded vehicle weight of 9,350 lb, the subtraction 12,000 − 9,350 leaves 2,650 lb before other towing limits.
That remainder is 850 lb below the receiver’s published drawbar figure. It is not a towing approval: confirm the chassis instructions, axle and tire loads, receiver, tongue load and towing equipment. Added passengers or accessories can change the result.
Walk through the layout in travel condition
Close slides and test access to the bathroom, refrigerator and emergency exits. Count approved travel seating separately from beds, and check restraints and child-seat compatibility for every intended passenger. A factory cab does not prove that every coach seat has equivalent protection.
Check the highest actual travel equipment and parking approach rather than assuming a van fits an ordinary garage. Read license requirements independently of the RV’s marketing class.
Choose gas versus diesel only after the required layout and loaded ratings are established. Compare a towable alternative if you need to leave the living quarters at camp.
