Ok, here's an update.
I checked the power at a pole about 5 spots closer to the transformer, and it was 10V higher than ours. So we moved.
PLUS, we have a Progressive Industries EMS-PT50C external UPS, a current product. Ours is about 4 years old. When I check the park's 50A outlets with my Fluke voltmeter, it reads about 5V *higher* than my UPS shows. So, if the UPS says it sees 110 coming in, the Fluke shows 115 coming in. So it may be that, even though the power is a bit on the low side, the UPS may be shutting down power to the coach too soon. So, does anyone know....do these UPS's need to be calibrated? I can't think of any other reason that it and my voltmeter would be 5 volts apart.
