Query: Maxxair Turbo/Maxx Fan

Easy Install. Thermostat works very well. Moves a pretty good amount of air, which cools off our hot fifth wheel in a respectable amount of time. A bit noisy even though the fan is on the outboard side of the vent cover, but it is not so bad as to be annoying. Overall, it's a good purchase.
