well new tires are on, lost one wheel cover(tag axle) on the way home . does any one have one? new Napa batteries! new axle seals! now for the leveling problem.. so when the coach is running it levels out fine (switch in drive) turn the coach off and about 5 minutes the right rear is all the way down . I turn the leveling adjustment to right and push up and she goes up... wait about 5 minutes back down .. I don't hear any air leaks soooo I am thinking the leveling valve is not holding air pressure and is bleeding back to the tank? your thoughts?
