On our 2015 Fleetwood Bounder 35K, when parked in our driveway, the home GFI breakers trip, when ever we plug in a 120 v power cord from the coach.  The two home GFI circuts have a 30 amp and a 20 amp breaker.  Just trying to keep a 5 amp coach frig cooling down before a trip.  This did not happen, when we plugged in our previous Class A coach.
