20ft Steel Frame Caravan

The twenty-foot version, on the same heavy chassis and off-road wheels. Insulated, with kitchen and bathroom, in a body you can tow behind a serious vehicle rather than book a truck for.

The trade against the 40ft is floor area for manoeuvrability. If the tracks you use are tight, or you expect to move it more than once a year, the shorter body is usually the right call even though the price gap is not large.
