I have a 3 way fridge in a 2017. My VW Touareg might take care of about 1/2 of that 11 amp draw from my stock battery. So, every hour, I'm losing about 20 percent of my usable battery capacity. So, on short drives, when I know there is plenty of sun waiting at the campground, I might run the fridge on 12V. I've seldom done that, however. The fridge, all by itself, is an excellent cooler. Some ice bottles will keep it fairly cold. I don't camp with much food that can spoil, so I don't worry much about it. On propane at the campground, the beverages stay cold, the butter is too hard, and everything is good.

And then we keep a couple of frozen bottles of water in there to keep it cold on the road.
