Randy, We have finished the installation of our “Cool Blue” and are extremely happy. We have 4 cu ft of freezer and 4.6 cu ft of refrigerator. We have reached -17F in the freezer! We found that keeping the dial at 2 keeps the freezer just above zero and the fridge about 40! I thought you might appreciate the attached pictures. Feel free to use them in your book. I am working on a technical article I would like to submit to some boating magazines. I will keep you posted.
