Abstract: An elongated plywood panel serves as a base member for storage cabinets mounted onto the forward or inner end of the base member. The rearward or outer end portion of such base member functions as a table. A track structure is provided below the base member and supports the unit for sliding movement between a stowed position within the bed space of a pickup or the like and an extended or use position in which the table projects rearwardly from the bed space of the vehicle. The cabinets may include a pair of side cabinets which are hinge connected to a central cabinet, for movement between a storage position in which the side cabinets are in juxta-position with each other and the central cabinet and are positioned over the table, and a use position in which the side cabinets extend laterally outwardly, in a wing fashion, from the opposite sides of the table and from the access opening for the central cabinet.
