All of you are right. I was reading the operational manual wrong. It states a warning indicator will sound and a dash panel warning will appear at approx 60-65 psi. I am now going out to see how the gages are calibrated as I have never had a dash or audible warning. The OM doesn't address a max air pressure. I'll be calling the factory first thing tomorrow's AM.
I have to find a shop that will work on rv's. I live in small town NW TN and all shops here will do oil and lube but will not touch any mechanical problem. I cannot physically do the work myself. That's a bummer.
Guess I am out of commission til I get this thing fixed.
