Best guess is it would be a reasonably doable project. You might call the factory and talk to Bryan or Rick to get dimensions confirmed. I don’t know if there is DC circuitry going to the air conditioner that will be of sufficient size to handle the fan. What’s there is probably small, like 22 gauge for the thermostat, but you should be able to repurpose the shore power wiring to handle the fan.Taku said:Looking at a used Alaskan, but would want to remove the air conditioner. How hard would it be to seal up the opening? Maybe replace with a Fantastic Fan? Thanks.
