12 volt refrigerator nova cool skinny big fridge's

I have a Novacool that I installed in place of th Dometic 3 way. its the 4500 model and fit fine. It ran for 4 months straight through Mexico and Central America, the high heat but mostly humidity meant it was running more than I would like, but I didn't have time to insulate around it before I left and didn't defrost as much as I should have. I would never go back to a 3 way fridge.
