Abstract: Retractable stairs for mounting in an exterior doorway of a recreational vehicle are provided with a spaced apart stringers and a tread extending between the stringers. Spaced apart straps are connected to upper ends of the stringers and are pivotally mounted to a floor in an interior space of the recreational vehicle to allow movement of the stringers and the tread through the exterior doorway between a retracted position stowed within the recreational vehicle and a deployed position outside of the recreational vehicle. A threshold plate is positioned between the straps and is fixed against movement during the pivoting movement of the straps. Locking latches extend outwardly from the stringers and are positionable for engaging a jamb of the exterior doorway for releasably securing the stringers and the tread in the retracted position. Extensible support legs are mounted on the stringers and extendable downwardly below the stringers to engage a ground surface for supporting the retractable stairs.
