Are you going to run a 4" duct to the head or something smaller? I installed an AC this winter in my Marlin. It's a 1994. According to the factory manual for that year they did not have AC going to the head. I would like to run a 2-3" duct to it due to space limitations and the limited cooling area in the head. I was thinking if I could find a small and quiet exhaust fan I could cool the head that way instead of running another hose. All I would need to do is add a vent from the head to the cabin. The exhaust fan would be mounted high in the head area and suck in the cooler cabin air.
Would something like this work for you too?
