Abstract: A step assembly for use with a truck load bed has an elongated support member that can be inserted into a hitch receiver. The support is pivotally connected to a step that can be moved into several positions. In a rearward position the step is far enough to the rear of the body of the truck that the step may be stood upon when the tailgate of the vehicle is in an open, lowered position.
