A Class C motorhome is a type of motorhome built on a truck or van chassis with an attached cab section. They are recognizable by their over-cab sleeping and storage area, which provides additional living space for families of all sizes. Class C motorhomes are smaller in size than Class A motorhomes and can get better gas mileage, but they still offer many amenities of a larger Class A motorhome. They are often built on chassis similar to a pickup truck or a box truck, and the engine is always in the front.
