Driver Side of Coach Leaning 2 to 3 Inches

We are leaving tomorrow for Klamath Falls from Seattle to attend a dog show. When I opened the rv garage door I discovered the drivers side of the coach was leaning. I think the air suspension system is the cause. I started the engine and the air suspension leveled the coach. The coach was last used 5 weeks ago.

Could this possibly be a safety concern ?

Thank You

I had the same problem on mine, the left front would bleed off when parked. I know the dealer did drive it at least 2500 miles, probably longer, and it held up fine. The compressor had more than enough air to hold it up while the engine was running. I think when WRV built it, there could of been small piece of dirt that got in the line and was blocking something in the valve.

I got a new one (they had to order it)from Brake Systems Inc in Portland OR. My part number was Haldex 90554945. 503 236 2116. Cost 98.78. It was an easy install, 2 air lines and two bolts inside frame.

IIWMI'd run the engine & get the coach level, then shut it off & listen for air leaking. If I can't hear it leak on level ground, the air leak is slow enough there won't be an issue driving. It'll be a nuisance on occasion, but maybe an R&R w/cleaning and good inspection of the tubing ends will find the problem.

However, since the coach has been sitting for 5 weeks, I think I would sanatize the fresh water system so you don't get sick from contaminated water. JMTCW.

I forgot to mention, that mine I could hear slight air leak from the vent hose with the engine off. I could put my finger on the vent hose and feel a small amount of air coming out. However, the new one had the same part number but no vent hose. Maybe there was design problem. I could see no way to service it. Now it works fine.

The only I forgot to mention, was the ride height arm if you install a new valve. It didn't seem to make any difference in what postion I installed the arm to the valve. The arm just rotates 360 around. Then I adjusted the center of the arm to get the right height.
