Yachts: The height from the ground to the bottom of the lower frame member in front of the rear wheel is generally set to 12 inches. If the height is too low the control rod on that side's level control valve needs to be lengthened. If the height is too high the rod needs to be shortened. The level valves on my coach have a substantial dead zone in the center position, or it least it seems that way as they are very slow to do much unless moved radically. I've found I need to drive it a mile or so before the height settles into an ongoing position. The one nice thing you have going for you is that the valves are consistent in the height they are holding so it is highly probable the valves are fine.
