RV electrical
We just built a new house and I had a 20amp breaker put in. Went with a 20amp because the electrician said that should run 95% of RV's just fine, including AC... hindsight tells me I should have gone ...

Get one of these and test receptacle at the house. It could be wired incorrectly.
Circuit tester
If tester shows correct wiring at the house, it could be a bad element such as refer in the rig or a bad GFCI receptacle.
Turn off all circuit breakers in the rig. Plug into shore power. Does it trip? If yes, then there is a connection between the neutral and ground in the rig. Again element or GFCI receptacle.
If it does not trip, turn on main, then one branch circuit at a time. If one trips the GFCI it is on that circuit.
