(13) Now referring to FIGS. 2-4, alternative embodiments may further be provided with fastener holes or anchors on planar surfaces 6A and 6B corresponding to holes or posts on hitch ball mount 14. As shown in the drawings, clip pins 16 are couplable to corresponding holes of planar panels and hitch ball mount to secure the hitch ball in either a use, i.e., tow position shown in FIGS. 2-4 or storage position shown in FIG. 1. A feature of alternative embodiments of the present invention include adapting the height of the hitch ball by adjusting clip pins 16 to corresponding holes of tow accessory receiver 14 by selecting corresponding spaced perforations 8 of planar surfaces 6A and 6B securing the tow accessory hitch receiver 14 and inserting a clip pins 16 through respective aligned spaced perforations 6A and 6B and tow accessory hitch receiver 14. Insertion of a clip pins 16 holds tow accessory receiver hitch 14 in secure alignment.

(14) In alternative embodiments when planar surfaces 6A and 6B of step hitch assembly 10 are in stored, vertically aligned position, additional cargo or equipment carriers or accessories may be secured by pinning through horizontally aligned coupled perforations spaced along the edge of the step. Alternatively, a bicycle rack, cargo carrier, or other accessory could be mounted by fastening corresponding holes, hooks, clasps, bungee cords or other suitable fastener system through coupled perforations of the vertically aligned step hitch of the present invention. Thus, the adaptive design of the present invention facilitates detachable engagement of additional accessories to the vertically positioned planar panels when in tow or stored position, including, for example, pintle hooks or cargo carriers, bicycle racks, and boxes or cages for gear which may be fastened by a clevis pin and a secured clip pins 16 such as shown in FIG. 5 or any comparable commercially available fasteners, including any suitable pin, hook, clasp, bungee cord or other corresponding mated fastener component such as, for example, adaptable to detachably fasten additional cargo or equipment to the perforations on the opposing planar surfaces of the present vehicle hitch receiver.
