I boondock occasionally for a few days at a time and I have a built in generator, but my Norcold does fine for days at a time and hardly uses any electrical power. With a residential refrigerator I would have to run my generator several hours a day to keep the batteries charged, not to mention the wear on the batteries.
I don't see a residential refrigerator in my future. I know the cooling/freezing advantages, but just not for me.
