Abstract
A system and method are disclosed for leveling a vehicle when stationary. The system 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. The blind sides of the jacks in each zone are connected together. The rod sides of all of the jacks are connected to a common fluid line, which typically is at low fluid pressure or pressure-free. The method involves extending all of the jacks from retracted positions to extended positions until they meet the surface upon which the vehicle is located. Fluid is then applied to the blind sides of either the second or third zone leveling jacks to raise the lower of the two sides. If the front end is lower than the rear end, fluid is applied to the blind side of the leveling jack in the first zone. If the front end is higher than the rear, fluid is relived form the blind side of the leveling jack.
