I have an A126 so the fridge is small. We prechill the fridge at least 12 hours before leaving and pack with cold food items. We dont have a freezer compartment.
When we drive we use 12v for the fridge and it either maintains the cool or gets colder. Back to AC at the CG Or propane when boondocking.
I'm not comfortable with propane when driving.
