RV Class Differences

Motorhomes come in three different classes, designated by letters A through C. Each class is based on a different kind of chassis, but the differences don't stop there. Knowing your way around the advantages and disadvantage of RV classes can make a huge difference in your enjoyment when you do make your purchase. - Class A RVs are built on a bus chassis, and are the longest motorhomes available. Class A RVs come in lengths up to about 40 feet, though some deluxe models may be longer. They offer the most storage, with a base section that can hold luggage but, because of their size, they get the lowest miles per gallon. Class As are generally rolling houses, with bathrooms, separate bedrooms and even, sometimes, a split-level. Being a specialized vehicle, parts are often more expensive.
- A class B RV is built on a standard van chassis. Often called camper vans, these are the smallest RVs. Class Bs are seldom longer than about 20 feet, but they're also the lightest, the most maneuverable and get the best miles per gallon. Not all have bathrooms. If they do have a bathroom, it's unlikely to be plumbed-in -- port-a-potties are more common.
- Class C is the middle-sized type of RV. Its style is quite distinctive because there's a "cab-over" section that overhangs the cab. Class C RVs are built on a standard truck chassis, which means that they're a little easier to repair because all you have to do is find a dealer who handles your particular kind of engine. Class C RVs are available from about 19 feet to 36 feet.
