In all of these locations, it is generally illegal for people to ride in a travel trailer or caravan while it is being towed on a public road.
History
In Europe, the origins of travel trailers and caravanning can be traced back to traveling Romani people ('Gypsies'), and showmen who spent most of their lives in horse drawn trailers. The world's first leisure trailer was built by the Bristol Carriage Company in 1880 for Dr. W. Gordon-Stables. It was an 18-foot (5.5 m) design, based upon their Bible Wagons, which Gordon-Stables named "Wanderer". One of the first home-built house trailers in America was built by John "Jack" Anthony Porcella, grocer-barber-restaurateur-miner who travelled extensively throughout the western states. Modern travel trailers come in a range of sizes, from tiny two-berth trailers with no toilet and only basic kitchen facilities, to large, triple-axle, six-berth types.
