My fridge was on gas only. When I hit the battery dx switch the fridge went dark along with everything else in the camper, still wouldn't run. I guess i could look into hitting the breaker for the converter, but that kinda sucks, be nice to give the batteries a bump and not sure the converter is working when the battery disconnect switch is off anyway, or is it? Maybe it was just a combo of altitude and heat? Had about 6 in me, maybe I missed something, new to powering the AC with a genni. I'll try again when we heat up, but not with altitude.
