[Richard and Rhonda]

I have never been able to plug my coach into a 20 amp GFI circuit in order to run the fridge and lights when parked in front of the house without an instantaneous trip of the GFI circuit. The folks who make some of the circuit boards, PMMI, offered to sell me the "fix" for several hundred dollars. It seems the lights that indicate voltage and especially polarity, bridge across the two hot legs and trick the GFI into thinking there is a fault.

I am happy to report that plugging it into a NON GFI circuit works just fine.

Dang, now I can't justify to the CFO, running a 50 amp circuit to the front of the house.
