Airspring air loss issue...help!

[Fairlane1]

I have a 1999 American Tradition. Whenever it's been parked for about half a day, it loses air at the front end (front end droop). We've checked just about everything that is reachable underneath (including the lines, valves, and the airbags themselves) and performed the old "soapy water" test. We did find what appeared to be a couple of very minor valve fitting leaks and attended to them, but the overall leak persists. There are a couple of valves located way up at the body area that we couldn't readily access. Short of tearing up the floor and accessing them from inside the coach, (horror!) I'm not sure how these are serviced. My '57 Fairlane looks great with a slight rake. My Tradition does not! Has anyone had a similar experience? If so, what was the prognosis? Thanks for your advice, Dan

guess not.. mine does the same thing, just thought it was normal, I think mine comes from the rear tank drain, as i leave it open slightly to purge water from the system.
