Kinda/sorta.
There is no transfer switch.
Right now I plug the fridge into an outlet that is under seating. The outlet is somehow rigged to the inverter. I flip the inverter "on" and I'm running on 12v.
When I get to the campground, I unplug my fridge from the outlet under the seat, flip the inverter switch to "off" and plug the 30 amp shore cord to the shore power.
The inverter is not in play at all when I'm camping.
FYI: I don't do shows or fair. I camp with my horses and trail ride. Now that's bringing a pet along! lol
yes i know you think you don't have a transfer switch
BUT unless you are physically plugging the fridge into ANOTHER outlet
there is already a TS installed and in use
OTHERWISE that unused cord from the fridge would be 'electrically hot' and a real danger
IF you are moving the fridge cord from inverter outlet to shore outlet, all you need to install is a transfer switch
moving the fridge cord is the part you have NOT clarified
