A truck bed lift system is provided that includes elements for positioning a truck bed at a predetermined height and angle. The system has means for sliding the truck bed relative to the truck frame, means for lifting the truck bed, and means for tilting the truck bed about a pivot point. In addition, elements are provided for retracting a bumper guard so that it does not impede a downward tilting movement of the truck bed. Methods are also provided for transferring an object between a loading platform and the truck bed when the truck frame and the loading platform are noncoplanar.
