In my Alaskan for a refrigerator/freezer I went with the NovaKool R3803 that is a good size (100L) and can sit lower than most since it has a stepped back and the compressor on top. Made to fit the hull of a boat but works well for truck campers. It is DC/AC but I went with DC only since it it is cheaper. For your application if you are only using the camper for duck hunting a chest type DC fridge may work just as well since you don't need the size for a day or two and it can be removed and used for other things. Another option would be a truck fridge that are smaller and cheaper. Here is the NovaKool: https://www.suremari...25/R3803DC.html
Thats a good idea. i ordered a iceco chest style. I can use it here and in the boat!
I also just picked up marine paint from sherwin williams. Its catalyzed so should hold up well.
