Abstract: A portable staircase includes a stairhead that can slide along a support track to extend and lock the stairhead away from a vehicle. The staircase can further be locked in either an upward storage or downward use position. Vertical support frame members provide support to the staircase when in the downward use position. A further embodiment of the staircase includes a vertical support frame member cover, along with a plurality of moveable vertical support frame members used to move the staircase into one of three positions: front-, right-side-, or left-side-facing.
