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. They are also called motor home and motor caravan. 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. RVs can also be rented in most major cities and tourist areas. Furthermore, they are also 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.
