Ambient temp is the key.
I have my fridge set to 33 degrees. I can go ~30 hours before the fridge shuts down in a +100 degree environment. I would expect to almost double that at 50 degrees.
I use my fridge everyday, so I leave it running 24/7. I've already saved ~50 dollars on bottled water in the last few months.
When I'm home [garaged], I plug into house power [Wil at Sierra Expeditions gave me the idea] via an extension cord [will someday run a dedicated cord to the front of the truck]. The fridge [current 50qt ARB] makes the switch to 110 automatically.
