A class C motorhome is constructed using a cab from a large truck or freightliner with a travel-trailer style body mounted onto a long hauling chassis. This type of RV usually has an alcove above the driving cab with room for one or two extra sleepers. Many also have sliding panels, a convertible sleeper sofa, and a separate bathroom area. A separate living area with a larger bed is also common.
These salvage recreational vehicles are popular for people who accommodate a lot of people while camping as they can comfortably sleep four to six people in the average-sized models and up to ten in the larger sizes.
