A pick-up truck bed toolbox system utilizes a tool storage box which, in its stored, stationary position, rests on the floor of the bed of a pick-up truck such that it is parallel to the side wall of the truck. Electric motors, which can be remotely operated, are utilized to rotate dual, upstanding screw shafts which are connected via laterally extending cantilever arm members to the front and rear ends of the toolbox. The screw shafts raise the toolbox from its resting position on the floor of the bed of the pick-up truck, to an elevated position over the floor, and the shafts then operate to move the arm members laterally to extend the tool box to a position passed the side wall. The screw shafts can then be activated to lower the tool box to a lowered position outside the truck, adjacent to and alongside the sidewall, thus providing easy and ready access to the toolbox. The same system is utilized to return the toolbox from this lowered position outside the truck, to the floor of the truck bed.
