Abstract: A receiver adapter comprising: a hitch post including: (i) a stable post and (ii) a bias post that is movable relative to the stable post between a removable position and a locked position. The receiver adapter may include a bias member that extends from the stable post to the bias post and, upon movement of an adjuster, the bias post moves relative to the stable post to increase a height or a cross-sectional thickness of the hitch post.

Abstract: A side bar and steps attached to the side attached to a vehicle or to the side of the vehicle by gears, ratcheting teeth or other movable engagement to the side bar or vehicle. A step is constructed by attaching a curved or flat member to the top of an L-shaped support bar that is in turn connected to the side bar or vehicle. The steps are movably affixed to the side bar or vehicle via ratcheting teeth or gearing. The L-shaped supports have a plurality of engagement points so that the step can be adjusted upward and downward using the different attachment points on the gear or ratchet. In this manner steps can be moved for different users depending on the height of the vehicle or user preference. The L-shaped support bars may be flared outward and provided with a plate for mounting the step thereon.
