Amphibious Trailer

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 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.
