Why in a brand new building did you put a 15/20 amp gfci outlet in for the camper. A 30 or 50 amp outlet does not need nor is required to be gfci.
If your RV trips a GFCI, there is something wrong with it. While a 30 amp receptacle is not required to be protected by a GFCI, you may find campgrounds that have them on all the receptacles, even the 30 amp ones. For example, check the Trail of Tears State Park in Missouri.
The leakage that is tripping the GFCI will become a shock hazard if your ground wire fails and you place yourself between the vehicle frame & the earth. While the leakage may be small enough to not kill you since it only takes 5ma to trip a GFCI, it only takes around 100ma to stop your heart. If your RV trips GFCIs, find the problem & fix it.
