Abstract: A toolbox system for pickup trucks that provides toolboxes or storage units are equipped with a guide track receiving a plurality of rollers to allow them to be extended out of the tailgate of the truck bed for easy access. The invention can be used with or without a bed cap. The guide track and rollers, similar in appearance and design to a heavy duty drawer slide system, is mounted on each side of the bed near the top edge of the bed area. The toolbox or storage system with drawers, conventional in design, then moves along the gide track. The toolbox or storage system may then be moved from its stowage position behind the cab area, by releasing a locking mechanism and sliding the toolbox to the rear of the bed. There, tools and other items can easily be removed without climbing into the bed area.
