A travel trailer or caravan is 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.
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.
In the United States and Canada, the history of travel trailers can be traced back to the early 1920s, when those who enjoyed their use were often referred to as 'tin can tourists'. As time progressed, trailers became more livable and earned a new name in the 1930s and 1940s, which was the house trailer.In the 1950s and 1960s, the industry seemed to split, creating the two types that we see today, that of the recreational vehicle (RV) industry and mobile home industry. Today travel trailers are classified as a type of RV along with motorhomes, fifth wheel trailers, pop-up trailers, and truck campers.
