In the United States, it is generally illegal for passengers to ride in a travel trailer, while in motion, unlike horse-drawn trailers and coaches. Triple towing is not allowed in some states, such as California, Alabama, Florida, or New York; however, triple towing is permitted in Texas if the combined length does not exceed 65 feet (20 m)).
Fifth-wheel trailers
A 'fifth-wheel' is a travel trailer supported by a hitch in the center of the bed of a pickup truck instead of a hitch at the back of a vehicle. The special hitch used for fifth-wheels is a smaller version of the one used on 18-wheeler trucks and can be connected by simply driving the tow vehicle under the trailer. Fifth wheel trailers are popular with full-time recreational vehicle enthusiasts, who often live in them for several months in one place, using their pickup truck tow vehicle for local errands. A fifth wheel trailer tows more securely than a traditional travel trailer because the hitch weight sits directly over the pickup truck's rear tires. Since part of a fifth wheel sits over the bed of the pickup, it also reduces the overall length of the vehicle/trailer package while allowing the same room as a comparable length travel trailer. Additionally, the hitch's location in the pickup's bed reduces the risk of jackknifing and allows for more manueverability when backing. Because of the greater room available on the roads in North America, these vehicles are more popular in the United States and Canada than in Europe or other parts of the world.
