Did the fridge need tinkering and can I prove I helped it? No. It's a good product. The shelf is just a little too warm for lunch meat and the area around the fridge stays very warm when it's tucked away in the van. I did the paper demo because it was very obvious the air was rushing below the fins instead of thru them. I proved the compressor stays hot for 25 minutes and between cycles only because I had the tool. My bet is they left out a hidden heat shield above that compressor to save cost. I mean that foam fit like it was made for it and I had fun opening it up.I am impressed. Generally, I don't re-engineer things until they fail the first time stock.
I am curious though, did you do any before/after measurements to prove out your mods, or are you just going with the general idea that better is better?
