I can explain this, maybe. :-)

When you level the coach, the leveling system is supposed to isolate the ride height valves. IF the solenoid valves that provide the isolation lea by, then remember the ride height valves are trying to undo the leveling you just did and restore ride height.. So if you have raised one end the ride height valve is dumping the air to the atmosphere. Hope that made sense
