An extendable load bearing apparatus that protects the bed of a pickup truck from damage caused by unloading and loading objects into and out of the bed, and that protects the bed from otherwise compromising weather-related elements. The apparatus includes a load bearing tray that has longitudinal sides, a forward end, and a rear end, and that has downwardly projecting tray supports extending substantially along the longitudinal sides of the tray. The apparatus also includes a plurality of rollers each housed within a roller bracket and secured to a workpiece. Each of the plurality of rollers is in supporting relationship with one of the pair of downwardly extending tray supports. At least one axle extends transversely from each of the pair of downwardly extending tray supports. A wheel is mounted in rotatable relationship to each of the axles to facilitate movement of the load bearing tray in a longitudinal direction. A pair of channel brackets is secured to the workpiece, with each of the wheels being housed within one of the channeled brackets to limit movement of the load bearing sliding tray in a longitudinal direction. The rollers and the wheels function as load bearing members that support the sliding tray to maximize the load bearing capability of the sliding tray regardless of the position of the tray in relation to the pair of channel brackets.
