Abstract: A pickup truck toolbox device is accessed from the sides of the truck through side sliding doors that open and close simultaneously and lock down. The toolbox provides a rolling tray that slides toward the user for easy access to material stored in the tray, or away from the user, and partially out the far opening, to allow for access to a large storage area below the tray. The tray also converts to a rolling cart to transport tools and material to an area away from the truck. The entire toolbox sits on the side rails of the truck and is elevated above the bed of the truck, keeping the bed free for transport of longer items.
