Thank you so much for the reply. My Progressive is right next to breaker panel and the readout is just above the panel. It cuts out properly at 104 vac on either phase and the voltage readout agrees with my 2 other meters. I see swings from 126 vac to a low of 102 vac. Line Voltage changes are sudden likely due to the other autoworkers and the Grand Design EMS shutting of their coaches at 108 vac. It seems like my Montana is one of the smaller users as some neighbors have 3ac units. Thanks for mentioning the Hughes Specs. I had forgotten to see if it handled the voltage range. I am forced to turn off the progressive at times when the voltage is see sawing and go into manual energy management. I lost my Splendide motor control board when I forgot to shut it off when the progressive was shutting down every couple minutes. I will put the Hughes at the park pole.

Thanks again for your advice.
