All - It may have been covered, but just for the record. A GFI will always trip on an RV because the RV is not grounded internally, it get it's ground from the pedestal power, or in this case the house 15A receptacle, a GFI senses a wiring discrepancy in the unit, and trips which is what it's designed to do, it's working fine, too many trips and it gets weak. A 20A receptacle is also not strong enough to power the coach even if everything is off, because the inverter/charger will draw almost that amount of amps to recharge the batteries. So power off the Inverter/charger by throwing it's breaker, then turn off breakers on all the other stuff, except the refer, then it will be fine.

An RV is not wired like a house, and should not be confused with the same kind of wiring a house has.

We replaced our household electric water heater with a gas unit, and I used to old connection, sans the second hot wire for a RV 30 AMP hookup. That allows me to run most of all the stuff in the RV except both A/Cs and the microwave at the same time. A 50A is what I am going to have at the farm, but here at home the 30A works fine.

I hear everyone say you can't plug an RV into a GFI outlet. We've had our RV plugged into a GFI protected 15 amp outlet for over a year now. We always have our residential refrigerator and the inverter/charger on and have experienced no problems..

Not all who wander are lost.

My first 3, 5ers I never had an issue, #4 tripped the GFI the first time at the house. Called the dealer and they sent me another convertor/charger, new unit acted the same, consulted with the factory, they said it was normal. Current coach trips GFIs.
Stopped at a friend's place in Montana, said I needed to run the cord into the garage; he said" no you don't; this has worked on every RV , I've owned. " He manually tripped the GFI with the test button , plugged in my cord adaptor and re-set with the cord in.
Three days on that outlet and it never tripped.
Different coaches, possible slight wiring or parts suppliers differences. But if you ask around, most units trip a GFI.
