A box body is normally an enclosed body with a roof.� At its simplest, it's a van.� Most of those fitted to military soft skins house radio equipment, workshops, printing presses and other things that need protection from the weather or better insulation than a canvas topped lorry could offer.� A common British military term for this type of body is "house type".
Open bodies like pick-ups are often called cargo or GS bodies but there are no fixed names for vehicle bodies.� British and American expressions often differ so that, for example, an open topped pick-up body might be called a cargo box in US parlance.�
