Abstract
Storable stairway and platform apparatus for recreational vehicles including a horizontal channel member mounted to the side or end of a vehicle beneath and extending to the side of the door, the channel member reciprocally receiving a pair of slider members; a platform pivotally engaging the slider members; and a stairway pivotally engaging the platform. The stairway is provided with a pair of opposing scissor linkages for folding the steps of the stairway into compact parallel abutment with one another and with the platform. The platform and stairway laterally slide away from the door and are pivotal into a vertical position for storage against the outside wall of the vehicle. The scissor linkages provide for unobstructed steps in addition to superior compact storage. Adjustable levelers are provided on each of the opposing scissor linkages to accommodate for uneven ground support. A novel bannister foldable and attachable to the side of the platform may also be provided.
