I know some guys build their deer coolers and use a window AC unit to cool it down. I'd like to know if they have any issues with icing up, and if so what will I need to do in order to address the issue? I plan on the cooler being a 4' cube on the outside with either 1 1/2" or 2" EPS foam for the side walls and some ripped down 2x4s for a skeleton frame on the inside. I plan on trimming the outer edge of all the EPS sheets with 1x4. I also plan on building a partition to go inside it out of 1/2" OSB and a few scraps of 1x4. The goal is to have a cooler that will hold 2 pretty good size deer (skinned and quartered) and get them down to around 34 degrees while the weather is in the 70's or even low 80's (early archery season). The cooler also must break down so that it can be stored in the shed, attic, or where ever he can find room in the off season.
I have a small chest freezer that I installed a secondary adjustable thermostat on, and it works well for me. It's just a pain to load it into the truck and haul it 50 miles down the road to his house "just in case" one of us gets one that weekend. Plus, during archery season I hunt closer to home most of the time, so he needs his own
