Brad, Where is your aux air compressor? I am not sure where mine is on my 2009 Camelot 42 PDQ. Might not be exactly same as your QDP, but a place to start looking as mine does not come on either. Thanks!
Vito, I ran engine, built up air and was able to raise coach over 5" That was 4 hours ago, maintaining that height. Will check again tomorrow. Also, not sure at all where aux air compressor is located. Any ideas? Thanks!
Martinvz, I think my Lipert Hydro tank only works the front 2 slides (I believe the rear 2 slides are 12 volt electric motors, the front 2 Hydraulic. I do have a hydro oil leaking out of the back motor bushing, something I believe I have had since coach was new. That system, I don't believe, controls ride height however.
