Abstract: An operating mechanism for a ramp door includes a door actuation system and a limit stop system. The actuation system is connected between the door and a frame or the vehicular structure directly and is operable to pivot the door between closed, deck, and ramp positions. The limit stop system selectively limits the pivoting of the door to a range between the closed and deck portion or to a range between the closed and ramp positions.

Abstract: A recreational vehicle (RV) includes a ramp door configurable as a ramp or as a patio deck. A stair is attachable to a side of the door. A railing extends about the perimeter of the door when in the deck configuration. First and second support cables may be connected between the door and the RV to support the door when in the deck configuration.

Abstract: An equalizer for a suspension system includes a pivot arm pivotably connected to first and second plates at a pivot point, first and second bump stops connected between the first and second plates on one side of the pivot point, and third and fourth bump stops connected between the first and second plates on the other side of the pivot point. First through fourth shock absorbers are disposed between the pivot arm and the first through fourth bump stops, respectively.

Abstract: A system includes a structure having a wall, a doorway and a door that is repositionable between a first position wherein the door is clear of the doorway and a second position wherein the door occludes the doorway. The system also includes a stair carrier attached to the structure. A stair may be connected to the stair carrier. The stair carrier is repositionable between a first position wherein the entirety of the stair carrier is disposed on a first side of the wall and a second positon wherein a portion of the stair carrier extends through the doorway to a second side of the wall. The door is fully operable between the first position and the second position both when the stair carrier is in the first position and in the second position.

Abstract: An equalizer includes a pivot arm pivotally connected between first and second spaced-apart plates fixedly connected to each other. First and second bump stops extend from one of the first and second plates to or toward the other of the first and second plates. A first shock absorber is disposed and selectively compressible between the pivot arm and the first bump stop. A second shock absorber is disposed and selectively compressible between the pivot arm and the second bump stop.

Abstract: A tie down track in the form of a five-sided structure having a top defining a plurality of holes therethrough and four walls extending from and connected thereto is formed monolithically.
