  • Patent number: 5188379
    Abstract: A plurality of hydraulic jack assemblies are located adjacent the wheels of a recreational vehicle. The jacks are initially extended until each jack contacts the ground with a relatively low initial pressure. Thereafter, the jacks are individually actuated as necessary to bring the vehicle to a level position. After leveling, the jacks are once again actuated to ensure that each of the jacks contacts the ground with at least the predetermined pressure. A relatively large, circular foot pad is fitted to the bottom of each jack to distribute the contact force over a relatively large area of the ground. Each of the hydraulic jacks includes a bracket, having a three sided channel member, for receiving the lifting force developed by a hydraulic lift cylinder and for transferring the lifting force to the frame of the vehicle. A hand held controller having a relatively long extension cable, permits operation of the automatic leveling system from outside, as well as inside, the vehicle.
