I installed my 65L 2 way my self in my ATC and did a rather custom job of it. Every part of the fridge except the fan and coil area is sealed off with about 1" of multi-layer Reflectix insulation material and aluminum HVAC tape. The fan and coil are properly exposed to fresh air and no dust gets in. This simply works really well and I don't draw a lot of power at all. My fridge has been on full time since May and pretty much runs off of solar, no puking CO2 in the air for the sake of recreation. I keep it reasonably stocked so that helps too, always some ice-cream and frozen chicken in the freezer, LOL!
Anyway, that is my take on it...
