Since it worked at one time, then something has changed.
Do you have a combination gas/electric water heater?
The combination gas/water heaters have an electric heating rod that goes in the tank. Those electric heating rods can over time deteriorate and cause a slight electrical leakage or if you accidentally left the heating element turned on with an empty tank they will blow out causing enough electrical leakage to play havovc with GFCIs..
Other suspicios areas are the fridge heating element provided it has a absorbsion fridge and even sometimes the A/C unit develops a small electrical leakage to safety ground..
OR it just may be a GFCI failing, not unheard of but also not all that common either. For the most part they do live long lives, I have never had to replace any in my home and those are going on 30 yrs old now and only one in my RV which was located in a outdoor outlet box (which is not ideal place for electronics)..
Do you have more than one GFCI in your RV? Kitchen, bath and outdoors need to be protected with GFCI.. If you have more than one does both trip?
Sometimes RV manufacturers can be real cheapskates and make one GFI server bath, kitchen outdoor outlets plus sometimes run the fridge on the same circuit..
Quickest and cheapest way to figure this out is if you have shore power available that you can plug into or even a generator (assuming you don't have builtin gen).
