A camper built on a light truck chassis; a Class C motorhome in North American terminology. In North American English the term recreational vehicle, and its acronym RV, are generally used to refer to an enclosed piece of equipment dually used as both a vehicle and a temporary travel home. RVs are intended for everything from brief leisure activities such as vacations and camping, to full-time living, for which they are often parked in special trailer parks. (However, many trailer parks are reserved just for mobile homes, not to be confused with RVs/motorhomes.) RVs can also be rented in most major cities and tourist areas. RVs can also be used as mobile offices. When used as mobile offices they often include customizations such as extra desk space, an upgraded electrical system, a generator, and satellite Internet.
