my coach has two air ports in the passenger side engine bay. one at the back and that is the one to hook into to use shop air and i have my shop air hooked into there all the time. that said, you do not want to pressurize it up to much higher than 125psi. my shop compressor will do 175psi all day long, so i regulate it down to 125psi. this air port on mine does not have a valve.

there is a second air port at the front of the rear engine bay. it is valved and is an output for the air doubler that is installed. you do not want to use shop air there.

i carry a small regulator with short hoses on it to pressurize the coach from other peoples shop air if needed
