The invention is directed to a pick-up truck having a movable cover thereon. The side wall of the cover having rails at the bottom to accommodate a sliding motion. A hydraulic system is incorporated in the bed of the pick-up truck. The hydraulic system consists of a first hydraulic cylinder being mounted at a top of one of the sidewalls and covering half of the distance of the bed of the truck. A piston of the cylinder is separably connected to a rail on one side of the cover. The piston, when actuated, will move the cover half way along the cover. A second cylider is mounted at a half way mark of the first cylinder but on the opposite side of the other side wall of the truck. The piston of the second cylinder, when activated, will move the cover to its end position at the tailgate of the pick-up truck.
