What I'm suggesting is to eliminate the gfci on the inverter but have the refrigerator connected to another gfci - either one in the RV or one at your home (sticks & bricks). I'm not sure if the circuit for the refrigerator is wired through a gfci in the Montana - it should be. So, if it is not tripping another gfci, we can eliminate problems with the refrigerator. Thus making the problem the inverter.
