If I had a compressor refrigerator, I woul want at least 250Ah @12VDC of usable battery. That would require 4 6V golf cart batteries. You would also need some serious solar and/or a generator.
I'm not a expert, and my experience is not RV.
A friend had a compressor fridge installed when he bought his new '99 Pete. Working on his truck, I know he has the same batteries to crank his Cat as I used in mine.
One summer he had to leave the truck in a Texas truckstop, get home on the bird. It was 3 days before I got there to deliver the load. I planned to jumpstart the truck if needed. When it started, I grabbed a trash bag, so I could get the garbage out of fridge. Instead I stole a ice-cream bar.
Now that fridge was not very big, but his wife would send him out with enough precooked meals to last a couple weeks. He would only run the microwave with engine running.
I have taken the propane tank off the tongue, because the only installed use is the 3-way fridge. When traveling, the TV charging system will keep it cold. We camp at power post, so 120v runs the fridge. The only time I would run it on propane would be if we had food in, and stopped on the way between campsites. I'm working on hooking it to a 1lb bottle for those times.
