A retractable stair assembly for vehicles. In an embodiment, the retractable stair assembly may be detachable. Mounting brackets may be provided at opposing sides of a floor plate, and a one-piece mounting bracket assembly provided for installation at the threshold of a door in a recreational vehicle. Pivot plates are provided for pivotal movement of a retractable stair assembly about pivot studs provided on the mounting brackets. Pivot plates may be in the form of open jaw brackets provided at each side of a sill cover plate, to enable removal of the retractable stair assembly. A sill cover plate is provided that is shaped and sized to fit over the threshold and sill in a recreational vehicle doorway, yet allow closure of the door. In an embodiment a bottom stair is independently deployable, so the stair may be used, or not used, as may be appropriate at a given location. The independently deployable stairs are secured by an uplock and downlock operable with a latch which is biased in a closed condition at either the uplock or downlock position.
