Air Brake Pressure Issue

Hi all

anyone have this issue. I have a 2007 Coachmen Cross Country 354 dp. There are 2 PSI gauges on dash cluster. I'm told #1 is pressure for front airbrakes & #2 is for rear. After 2 hours or so of driving the pressure on #1 climbs to well over 150 psi. I stop turn engine off and release air pressure thru brake pedal, start up build pressure, no issues, then on my way. Freightliner and rv dealer say everything is working fine and they can't duplicate problem. Any suggestions as to what may be something to look into. I plan on having gauge replaced and go from there.

Air Governor

I would start with the governor... it at what air pressure the air compressor stops pumping. Sounds like it sticks at times.
