Welcome Audrey! Have you read the remaining 230 pages of this thread yet? :)
Gang, I installed the Progressive Industries EMS with the remote read out and it works perfectly, and happily reports no problems with my electrical system.
Another question, we used the rig this weekend and the initial run of hot water smelled like rotten eggs. I did not drain anything since we used the rig in August. Could leaving the water in the heater that long result in the smell? I winterized today and left the drain plug out so the heater could air out somewhat.
