ABSTRACT:
A ramp, for loading the box of a pick-up truck, has a pair of stringers and slidable rungs joined by lengths of chain. The stringers may be telescopically stored in storage tubes located on the box floor. The chains that join the rungs limit their separation when the ramp is extended. The stringers are tethered to the storage tubes when deployed and the storage tubes are optionally tethered to the truck box.
