Voltage variations and Surge cut off.
We are hooked up to 50A service. I just recorded the voltages at different areas and I will note them below. I have a Progressive EMS/Surge suppressor hard wired in just before the breaker box. It has...

Unless you have a (malfunctioning if automatic) autoformer, you aren't gaining voltage. Wires simply don't do that. It's entirely possible that the EMS's voltage readout calibration and your meter's calibration are out of whack with each other; as to which one is correct if either, you'd have to check against something with a known correct calibration to know.
It appears that you have a slightly resistive neutral connection somewhere, and the power imbalance caused by the air conditioner is causing it to track that leg a little and so give an unbalanced voltage. Cleaning the plug and making sure it's well seated in the socket would be a reasonable first step to try to correct it. Failing that, it's a matter of chasing down where the problem is, whether in your RV's wiring or the campgrounds, and hopefully getting it corrected.
