Abstract:
A system for leveling a vehicle which includes three zones with a first zone at the front end, and the second and third zones on opposite sides of the vehicle. All zones include leveling jacks, each having a blind side and a rod side. At least one leveling jack is located in the first zone, and at least two leveling jacks are located in each of the second and third zones, straddling the wheel on that side. The blind sides of the jacks in each zone are connected. In operation, once the vehicle is stationary, all of the jacks are extended from a retracted position to an extended position meeting the surface upon which the vehicle is located. Fluid is then applied to the blind side of one of the second and third zone leveling jacks to raise the lower of the two sides. The front end is then leveled.
