Abstract:
1. A system for leveling a vehicle when stationary, where the vehicle includes a front end and first and second opposite sides, the system comprising a. three leveling zones, with a first zone located near the front end, a second zone on the first side and a third zone on the second side, b. the first zone comprising at least one first zone leveling jack having a blind side and a rod side, c. the second zone comprising at least two second zone leveling jacks, each second zone leveling jack having a blind side and a rod side, and d. the third zone comprising at least two third zone leveling jacks, each third zone leveling jack having a blind side and a rod side, e. the blind sides of said second zone leveling jacks being connected to one another for equalizing fluid pressure therein, the second zone further comprising a second zone isolation valve operable to selectively isolate said blind sides of said second zone leveling jacks from said blind side of said first zone leveling jack and said blind sides of said third zone leveling jacks while simultaneously allowing equalizing of fluid pressure among said blind sides of said second zone leveling jacks, and f. the blind sides of said third zone leveling jacks being connected to one another for equalizing fluid pressure therein, the third zone further comprising a third zone isolation valve operable to selectively isolate said blind sides of said third zone leveling jacks from said blind side of said first zone leveling jack and said blind sides of said second zone leveling jacks while simultaneously allowing equalizing of fluid pressure among said blind sides of said third zone leveling jacks.
