HWH compressor pressure switch - what pressure?

My compressor makes about 65-70psi before the pressure switch cuts it off.  I've read that this is variable depending on the coach.  Someone in the Foretravel group on Facebook said told one guy it should make 110psi and if it doesn't, the pressure switch is bad, and this was a topic of discussion at the latest GV meetup.

Is this variable by coach and if so, where do I find what mine should be?

The 2001 had a smaller compressor and had a lower output as I recall and later they went to a bigger compressor like yours. Mine maxes out at 45 psi with nothing but a pressure gauge on it. It definitely on the back burner for my coach currently. Probably mod to a ARB compressor down the road. Remote mounted under the front of the coach outside.
The HWH manuals do call out the operating range

According to the manual, it should cut off at 90psi and back on between 70-80psi.  Just tested and it starts around 60-65psi and stops at 85psi, so it's only a few psi off it seems.  Should be fine.  Thanks for the direction Scott.
