My 2014 Tiffin Open Road rig has a brand new Dometic 4 door Refrigerator that still uses the vent fans that sound like high-pitched model airplane propellers! Since there is no solution, I placed a small, quiet fan inside the outside vent cover and run it continuously during the summer months. I hope this reduces the time the airplane propeller noises reverberate in the coach!
