A campervan , sometimes referred to simply as a camper, and also known as a caravanette, motorhome or motorcaravan, 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 coachbuilt body for use as accommodation. In the United States the term "recreational vehicle" (RV) is more common for these vehicles, and in that country they tend to be larger than in Europe and the rest of the world.Campervans may be equipped either with a "pop-up" roof which is raised during camping or a fixed roof, either shared with the commercial van that forms the basis of the vehicle , or as part of a custom coachbuilt body.
