X2 regarding emblethen's comments on the fridge in the slide. It took us an entire year, 1 replacement fridge, 4 different fan configurations and the installation of a curved sheet metal cap at the top of the shaft to get acceptable cooling. We also have dark paint so the wall has tremendous heat gain as well. After three units with roof venting and our current unit with side venting, we noticed an extreme difference in cooling between the two formats. We are currently looking to install a residential unit to get better cooling. As a side note, the manufacturer still has our original fridge in the shop where it has been running for three years at an extremely low temperature that it could never reach when it was in our rig.
