caravan is a trailer towed behind a road vehicle to provide a place to sleep which is more comfortable and protected than a tent (although there are fold-down tent trailers). It provides the means for people to have their own home on a journey or a vacation (holiday), without relying on a motel or hotel, and enables them to stay in places where none is available.Travel trailers and caravans vary from basic models which may be little more than a tent on wheels to those containing several rooms with all the furniture and furnishings and equipment of a home. They are used principally in North America, Europe, Australia and New Zealand and are rare elsewhere, so this article deals mainly with those continents/countries.Amy Coopercamper trailers
