A caravan, travel trailer, camper, tourer or camper trailer 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 trailer tents). It provides the means for people to have their own home on a journey or a vacation, without relying on a motel or hotel, and enables them to stay in places where none is available. However, in some countries campers are restricted to designated sites for which fees are payable. 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. Construction of the solid-wall trailers can be made of metal or fiberglass. Travel trailers are used principally in North America, Europe, Australia and New Zealand. In Europe, the origins of travel trailers and caravanning can be traced back to the travelling Romani people, and showmen who spent most of their lives in horse-drawn caravans. Samuel White Baker purchased an actual Gypsy caravan in Britain and shipped it to Cyprus for his tour in 1879. The world's first leisure trailer was built by the Bristol Wagon & Carriage Works in 1880 for William Gordon Stables, a popular author of teenage adventure fiction, who ordered a "gentleman's caravan". It was an design, based upon their Bible Wagons, used by travelling preachers in America's Wild West. Stables named it Wanderer. He travelled around the British countryside in it and later wrote a book documenting his travels in 1885 called The Gentleman Gypsy. This moved the Duke of Newcastle to commission his own caravan, The Bohemian. By the turn of the century, caravanning for leisure had become an increasingly popular activity. In 1901, the first dedicated caravanning club was established. The Camping and Caravanning Club (originally the Association of Cycle Campers) was founded by Thomas Hiram Holding, the father of modern camping. The Caravan Club was founded in 1907 with Stables as its vice president.
