As you know, air loss  on any coach with air suspension, along with air doors, toilets etc is a real challenge. We have a very simple 1984 Newell, and it is difficult to keep a tight rein on air issues  Any diesel shop can find your air brake loss issues promptly, but add the complexity of both systems, time for to parts to arrive that may be diagnosed as bad, and installing  them  can make a quick stop at the shop nearly impossible. Nothing worse than waiting for parts, and needed to get back on the road. Perhaps there are GURUS in your New York area that could lend you a hand after your trip ? Springtime   Good luck.
