Here's where I found a major air leak. Might be worth checking if you have a similar setup. The air line ran from the wet tank to an air hose fitting in the water manifold compartment. The line passed through a rough hole in the compartment wall with only silicone protecting it. Should have had a grommet. Probably been leaking for years. It was close to letting go completely. I eliminated the line altogether as I have never had much use for those external air connections. Takes a day and a half to air up a low tire!

......then again, that leak mighta had something to do with it.
Surprised you didn't have problems reaching "unload" pressure in your wet tank. Was your air compressor cycling on and off at a rapid interval, compared to your experience with your previous coaches?
You can speed up filling tires (with on-board air system) by setting your D2 governor up a bit. I have ours set to kick off at 130 psi, and it kicks on at around 105 psi. I run 100 psi in our tires, so I can top them off pretty quickly with the coach air hose.
Chuck,
I thought the same thing, the hose must have had a one way check valve at the wet tank.

About the same as the others. This leak may have become worse with all of the up and down and twisting I've been doing. I hadn't noticed it before today but then I've only had this thing a few weeks. No check valve; just a straight line from the tank. This coach has two of those air fittings, one on each side along with the wet tank dump valve. I'm leaving the other air connection for towing.
