Problem: Rooftop A/C unit does a good job cooling the galley and the cockpit area, but sleeper(s) don't get much of the cold air.
Solution: A compact, almost inconspicuous swing arm and a $12 Walmart electric clip-on fan. This system is situated in the perfect place to blow cold air back to sleepers in bed.
That is a cool install - thinking outside the box! I just looked at one advertised on Amazon, some guy installed one in a RT.....it cost $127.00 - ouch! Ron
