Hey, got a question about your A/C install. I'm going to do a similar installation.
Instead of cutting an intake vent hole in the roof, would it not have been better to cut a hole in the side, say close to the bottom of the fridge. That way, air could have been drawn around the back of the fridge to the A/C intake, helping to ventilate the fridge as well.
Great thread, I'm going to use several of your ideas...
