You should not plug your RV into a GFCI circuit. There are capacitors and MOV's in the RV converter that are connected between hot/ground and neutral/ground. A small amount of leakage in these devices will trip the GFCI. Sometimes you can get away with it. Most times you won't.
Have you noticed the 50 and 30 amp receptacles at the campground are never GFCI? This is why. Only the 20 amp outlet is GFCI and it is not intended to connect the RV.
