NO sweat - I was just pulling your chain - altho', I did cover this in post #7:
I had to remove the air line fitting that attaches to the fitting at top of the airbag, and completely cut off the end that is on the outside of the MH for adding air - so no way to totally check them for leakage prior to removal
Actually, I *had* unfastened and checked the outer fitting - using the "soapy water" method a few weeks back, with no evidence of leakage - and that was the reason I cut that end off to fully remove the airbag, I wanted to check the airbag end this time around to eliminate it as a cause - but DID have to unscrew it too, to get the airbag completely off the MH for a complete test. That meant I next had to re-secure that connector - and I made sure it was properly tightened at that point - and no leaks there after that.
ANYWAY, no sign of PSI loss overnight - so the somewhat looser tightness of that fitting probably was the leakage source - but that fitting is in an impossible spot to tighten with the airbag installed - OR to visually inspect, soapy water or otherwise - and certainly, NO way to check tightness with a wrench.
SO, I'll go ahead and install the new replacement airbag when it arrives next week - and keep this one as a spare after it's replaced...
If all this seems unusually lengthy, it's because some reading this might be interested in some of the finer details involved if "doing it yourself" - in my case, I'd probably have at least considered having it done commercially, in view of the unusual hassle this turned out to be, on my specific MH...
