A system for forming a retractable cargo support for use over the bed of a truck is disclosed. The system includes a slide system with an elongated slide base having an upwardly opening U-shaped cross-section, an intermediate slide that is slidably mounted within the U-shaped cross-section of the slide base has an upwardly opening U-shaped cross section, and a top slide. The top slide includes a downwardly opening U-shaped cross-section, and is adapted for nesting in a sliding relationship within the U-shaped cross-section of the intermediate slide. A load surface is attached to the top slide, so that mounting the slide base to the bed of the truck allows the load surface to be slid in and out of the bed of the truck.
