I guess I don't understand why you'd need to do this. If you'r driving, you can safely use the 12v source and the alternator will keep the battery charged.
If parked and using shore power or generator, the 120v will handle the job.
If parked and you don't want to deplete the battery, unplug the 12v or install a switch to shut off the 12v to the refrigerator or turn the fridge off
. You can set the voltage limit which will shut down the fridge when the DC voltage drops to the one of 3 settings. (manual, pg 34-5)
No need to also switch the 120v, it'll only work when it's available. My suggestion of using a DPDT switch would work, but as Joe (
