RE: Refrigeration.... the topic makes me HOT!
Hollywood, the power consumption of the Norcold is fairly high.* That's because the insulation isn't the best.* I don't know if you would want to take on the project, but I had a similar space to fit a refer on Delfin and built it myself.* I used vacuum panels and foam board for insulation, and Danfoss units.* I forget what the R factor is, but it is a whole lot higher than any off the shelf unit, so the power consumption is about as low as one can get.* I got what I needed, including the vacuum panels from rparts.com, which sadly looks like they are closing their doors.* There are differing opinions on cold plate vs. hermetic units like the Danfoss, but for simplicity and reliability, it is hard to beat the Danfoss units.
If you want the design drawings I did for my unit - about the same size as your sapce, let me know.
