help me decide on a refrigerator purchase

Almot I noticed you didn't include Norcold in your brands to check any reason for that ? The reason I ask is I was looking at a Norcold 3.1 cu. ft. 12 volt fridge with a Fuji compressor for $609.00 which is a decent price. It even has a stainless steel door. I know the main players for the compressors is Dornfoss and Fuji. Like anyone else I want the best quality I can afford. I also went on some marine websites and it looks like they offer larger cu. ft. within the same footprint so I may be able to squeeze in a 3.8 or 4.0 fridge. Unfortunately I don't think I can fit more than two batteries in my truck camper. Also because the LP cabinet dimensions I can't get more than a 20 lb. cylinder in there. I will continue to do research and watch for sales. I appreciate all the feedback from everyone thank you.
