I have a 2010 Tiffin Phaeton with a Powerglide chassis. Has anyone else had a problem with the Air Ride height? I have had the right passenger side air valve replaced 5 times because of leaks. It works ok for a while but when you park for the night or a few days, and use the auto level (which automatically drains the air out), it takes about 10 minutes to get the air back up above 120 PSI. I can hear the air coming out of the right front valve and that side of the coach will not rise. Sometimes after I get the air up, I turn the engine off, wait a minute, restart, then it goes up. If I stop for for fuel and turn the engine off, the right front goes down! Funny part is, once i get it filled again, it will work properly for the rest of the time-- Until we park and use the levelers. Could this be caused by the leveling system?
