Good afternoon everyone. First day on this site and first time posting a question . I have camped either in tents or some sort of camper my whole life. My wife and I bought a 2004 Prowler 5th wheel...
20 GFCI outlet tripping when you plug in your trailer......not uncommon for that to happen
RV Fridge electric element usual suspect
Turn the 120V AC circuit breaker for fridge outlet OFF (or unplug fridge power cord) then plug in and see if the 20A GFCI outlet still trips.
Otherwise turn ALL of the AC Circuit Breakers OFF....plug in and then close each individual CB one at a time and see which circuit causes trip of the GFCI outlet
