Abstract: An apparatus for automatically leveling a vehicle is provided. Having a plurality of legs, a sensor and a controller. The sensor is mounted to the vehicle to sense pitch and roll of the vehicle relative to a reference level plane. The sensor produces an orientation signal representing the vehicle pitch and roll. The controller is coupled to each of the legs and to the sensor, and monitors the orientation signal received from the sensor and in response to that signal the controller causes at least one of the legs to retract to move the vehicle downwardly relative to the ground surface, for orienting the vehicle with the reference level plane within a tolerance.

Abstract: A vehicle having an expandable slide-out body is provided. The slide-out body is movable relative to the vehicle by a slide-out apparatus. The slide-out apparatus has first and second rails, and first and second synchronization members. The first rail is attached to the vehicle and defines a first longitudinally-extending compartment. The second rail also has a second longitudinally-extending compartment. The second rail is attached to the slide-out body, and is disposed within and movable relative to the first longitudinally-extending compartment. The first synchronization member is attached to the second rail. The second synchronization member is located inside the second longitudinally-extending compartment and is engagable with the first synchronization member.
