Have you tried to run refrigerator on the trucks inverter?
Is this factory inverter?
Curious about factory on board inverters I looked around for info.
Appears 400 watts (300 while driving) which would be enough to run a fridge but Ford videos also states max load of 3.6 amps, and not to use as constant power source?
Not sure how rated 400 watts is limited to 3.6 amps?
Also found a lot of folks with voltage issue as the on board inverter is 110 volts and equipment looking for 117-120 volts would fault the inverter.
If persuing might be worthwhile installing a dedicated inverter
