The4js, on your 39K all your 110V breakers will be in the panel at the foot of the bed. Did you try turning them off and back on one by one? I just checked the GFCI in our 39K bathroom and it only controls that outlet. If you have the info on the Dimensions inverter, it might give you a clue. There is a 30A breaker on the front of the inverter. Hope this helps.
