I already have a fan in the stack, a fan on the inside coils for my refrigerator. We camp in temperatures above the 105 mark quite often. Knowing that 4th of July weekend was predicted to be between...
I have fans in the vent stack, controlled by thermostatic switch. I added 2 120MM computer fans to pull air across the coils at the top vent (pushing hot air out the top vent).
This past weekend, I was in close to 100 degree heat, and nearly the same humidity. Fridge still struggled, although the added fans on the top did help. I think I will try getting another vent and try what you've done to see if that helps more.
