thanks all. I presume it's a bad inverter. I have turned the main breaker off in the trailer and the fridge breaker off. I then turn the main breaker on. No problems. Immediately the gfci trips when I turn on the fridge breaker though. I have read about voltage leakage causing a gfci to trip. The romex wire from the fridge had a white, black, and bare copper wire. I wired these to the inverter with white-white, black-black, and green to bare copper. BUT, if the other end of the romex is wired incorrectly, making my connections wrong now on my end, would this cause the gfci to trip? I would guess there would be circuit breakers tripping if that were the case though.
