Hi there, I do not have a Georgetown but have had 2 x class A motorhome with residential fridges installed. In each case, the 110 is supplied from the inverter - they do not like being switched on and off a lot. Both have had upgraded Inverter capacity and batteries.
As a rule, if you are dropping these in for service, turn the fridge off to prevent possible brownout on the batteries that may damage your fridge.
