Abstract: A substantially total-needs rack system for extending the uses and the capacity of pick-up trucks provides a basic frame for rigid securance to the cargo area of a pick-up truck body with a matching assemblage of components and accessories that can selectively be installed on the basic frame through use of quick-attach/detach pins; some of the assemblage co-act together, others are usable only singly; among special cargoes that can be carried are panels, ladders, general elongate shape cargo, miscellaneous small items, and lengths of pipe which can be secured in racks by padlocks to prevent loss.
