A tailgate system for a vehicle comprises a tailgate pivotally mounted to a vehicle body for movement about a generally horizontal pivot axis between an open position and a closed position. The tailgate has an access opening configured to provide access to a vehicle bed area when the tailgate is in the closed position. The tailgate also has a movable tailgate portion movably connected to the tailgate. The movable tailgate portion is configured to cover the access opening in the tailgate when in a closed position of the movable tailgate portion. The tailgate also has a pocket opening for receiving the movable tailgate portion therein. The movable tailgate portion is slideably mounted to the tailgate for movement to an open position in which the movable tailgate portion is received in the pocket opening in the tailgate to uncover the access opening in the tailgate.

A agricultural vehicle includes a step assembly having a step and a tank that is movably mounted to the step. The step has a flat and horizontally oriented top side and an angled side extending from the top side. The tank is movably mounted to the step and is configured to move between a stowed position and a deployed position. In the stowed position of the tank, a first side of the tank is aligned with and parallel to the angled side to form a continuous angled surface. In the deployed position of the tank, a second side of the tank is aligned with and parallel to the top side to form a continuous horizontal step surface.

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.
