Abstract
Abstract A bed extension for a pick-up comprising a load-carrying beam substantially parallel to the rear of the truck bed supported outwardly of the truck bed by means of suspension cables. The suspension cables are attached to the load carrying beams at one end and to a rigid member of the truck body or frame at the other end and pass over vertical stakes which fit into existing or installed rear stake compartments of the pick-up. The load-carrying beam is stabilized by truss members which are secured at one end to the load-carrying beam and at the other end to the rear bumper or rear bumper support. The bed extension is removable or collapsible and is compactly secured together in its disasembled condition so as to be easily stored.
