Abstract
An improved enclosure for increasing the sealed storage capacity of pick-up boxes of vehicles that tow fifth-wheel camping or recreational vehicles or fifth-wheel utility or horse trailer vehicles is disclosed. The enclosure forms a weatherproof seal with the box in a manner that seals the entire box except for around the hitch and for a hitching access path from the tailgate to the hitch. A wear-resistant plate and flexible boot combination cooperate with a cradle assembly to provide a weatherproof seal and to direct rain out of the box. The enclosure assembly requires no connections with the towed vehicle.
