Here are some of the differences in Motorhome classes
Class A motorhomes are generally the top dogs of the RV world. Units range in weight from 15,000 to 30,000 pounds and stretch from 30 to 40 feet in length. Describing them as "motorhomes" is no exaggeration. Class A units come with almost every creature comfort you would expect in a home, minus the front lawn. They are frequently constructed on custom undercarriages or on a 3-10 ton truck chassis. Many Class A motorhomes also feature an automatic slideout. At the touch of a button, motorhome owners can extend a portion of their RV's exterior wall outward to expand their living space. Class A motorhomes usually provide cooking facilities, a refrigerator, heating, air conditioning, a self-contained toilet, water tanks (fresh water, grey water, black water), faucets, sinks, a LP (propane) gas supply, a separate 100-125 volt electrical system, and a full array of appliances and entertainment features. They can sleep up to eight people, depending on the model and the floor plan. Of course, all those features don't come cheap. Even low-priced models often top $100,000, and the upper end of the price range approaches $500,000.
Class B motorhomes, also commonly known as van conversions, are the smallest fully enclosed motorhomes. They are constructed on a van chassis with elevated roof lines but no modifications to the length or width of the original chassis. Class B motorhomes generally weigh 6,000 to 8,000 pounds and are 17 to 19 feet in length. Although living space is limited, Class B motorhomes receive high marks for economy, versatility, and handling. When not RVing, many Class B owners make use of their units as family vehicles. Class B motorhomes usually provide cooking facilities, a refrigerator or an ice box, heating, a self-contained toilet, a fresh water tank, a waste water tank, a faucet, a sink, convertible/folding beds, a LP (propane) gas supply, and 110 VAC and 12VDC electrical outlets. Class B motorhomes can sleep from two to four people depending on the model. Prices range from $40,000 to above $100,000.
Class C motorhomes, sometimes referred to as mini-motorhomes, are scaled-down versions of Class A motorhomes. They range in weight from 10,000 to 12,000 pounds and stretch from 20 feet to 31 feet in length. Class C motorhomes are generally constructed on a larger van chassis. The driver compartment is similar to a van, with a large box in the back. Class C motorhomes usually come with a sleeping bunk above the cab, in addition to a bedroom in the rear of the unit. Like their Class A big brothers, many Class C units feature a slideout to quickly extend the motorhome's living space. Class C units usually provide cooking facilities, a refrigerator, heating, air conditioning, a self-contained toilet, water tanks (fresh water, grey water, black water), faucets, sinks, a LP (propane) gas supply, a separate 100-125 volt electrical system, and a full array of appliances and entertainment features. Class C motorhomes can sleep up to ten people depending on the model and the floor plan. Prices range from $50,000 to around $150,000.
