132 volts is very unusual but can happen. But 4 parks in different states is next to impossible. Best thing is verifying with a voltmeter. Don't think I've heard of a PI EMS reading consistently high like that. A bad connection won't do that on 30 amps, 120 volts.
A multi-meter is a good tool to have in an RV. A permanently mounted LED display mini-panel meter is great too. It's a good idea to keep tabs on CG voltage. The EMS will shut you down but it helps to know what the voltage is trending at. If it gets too low, I drag out our Hughes autoformer. Have yet to see more than 121 - 122 volts in 7 states or Canada.
A call to PI is in order tho.
