I know this is an old thread, but here is my experience. My TT had a bad outlet that the fridge was plugged into. Not bad as in not working, just dampness would get into it in heavy rains (not obvious water) and trip the GFCI. The fridge is somehow wired through the GFCI which is located in the bathroom (not a real obvious link), so even on 12V only (we only boondock), the fridge wouldn't light with the GFCI tripped. Replaced the fridge outlet and all is fine. Also replaced the GFCI with one that has a green led when good and switches to a red led when tripped. Also wrote on the fridge outlet as a reminder that it was connected to the GFCI. This was the second TT I've had with a fridge not working due to a GFCI being tripped. Slow learner I guess :)
