Abstract: A vehicle hitch receiver mounted portable stairs fits a conventional hitch receiver of a pickup truck. An extended tongue fits the hitch receiver, secured by a hitch pin. The tongue is of a length that a pickup tailgate may be lowered to a horizontal position while the stairs attachment is mounted. The support has a rearward-sloping upright attached to the rear end of the tongue and ending in a flat horizontal plate. The plate supports a horizontal cross beam at its center, the cross beam supporting end beams to which the stairs is attached. The stairs assembly includes a series of horizontal stair steps supported at their ends by support rails extending upward at a rearward angle from the supporting end beams of the support assembly. An upper platform is mounted horizontally at the top of the stairs. A handrail may be added to the stairs assembly.
