I use my shop air all the time. At home I shut off the coach 110V compressor and just run the 12V to keep the slide seals inflated. I've always wanted to ask Newell, but forgotten, if they regulate their shop air down to 120 psi. Since the engine compressor regulates its pressure to 120 psi, I regulate my external air compressor down to 120 psi before I hook it up. Not sure if this step is necessary, but it makes me feel better. And I agree that only introducing dry air is important.
