Motor Home is a self-propelled vehicle that provides both transport and sleeping accommodation. The term mainly describes vans that have been fitted out, often with a coach built body for use as accommodation. In the United States the term "recreational vehicle" (RV) is more common for these vehicles. They are also called campervans.
Following is an example of a state statute defining the term:
"Motor home" means a vehicular unit built on, or permanently attached to, a self-propelled motor vehicle chassis, chassis cab, or van, which becomes an integral part of the completed vehicle, designed for human habitation for recreational or emergency occupancy.[Cal Civ Code § 1793.22]
