Re: Leveling system

So you can manually inflate and it will hold. All valves closed. When you select travel mode the travel solenoids open allowing air level to be regulated thru ride height valves. Three valves. One up front controls matching air pressure to all front bags. One left rear and one right rear. If your coach drops right low you have deleted front and left rear ride height systems. You have isolated to the Right ride height control system. Could be a bad ride height control valve or lines. If solenoid is failed closed it will not adjust up or down. Sounds to Me because it drops from full up solenoid is working but control circuit failed. Lines or ride height valve.
CAUTION operating the coach using blocks holding it at a similar ride height although drivable can easily over stress what the design limits were when built. Damage may result. I would NEVER operate with maintenance blocks in place in rear. Having one corner of the coach blocked up will exceed limits. This is way above drive height level. And the remaining level valves will be constantly trying to correct rather than being in balance. Broken windshields and structure damage may result. Twisting. If ride height blocks are being used understand that there is zero movement in the suspension at that location. Tires are your only airbag. Very easy to overload axles and tires if you drive thru anything. It is constantly bottomed out. If one Rear corner is blocked up at ride height the other two ride height valve still will operate if at similar heights as block. IMO.
