  • Publication number: 20080067775
    Abstract: A step for a large pickup truck has a tubular extension member having a square cross section. The extension member is sized to fit within the tubular end of a receiver type hitch. A stepping platform is attached to the top of the extension member. The extension member extends from the side of the receiver type hitch a sufficient distance to function as a step to the tailgate or bed of the truck. A ring on the extension member prevents it from being inserted too far into the hitch. A chain connected to the ring is attachable to the hitch to prevent the accidental removal of the step. The chain and ring can be positioned to allow the step to be moved between extended and non-extended positions.
