Some Fresh Air
I was not certain that I wanted a roof fan - I hate putting holes in a roof. But after reviewing it here I was convinced.
I opted for the MaxxFan 4500k. It has the automatic opening with a remote and it will close if it starts raining. I had this installed in the front flat area rather than in the back. I know you can get adapters to make it fit the ribbing but I preferred to install in a flat area of the roof that looks like its made for a sunroof. Like the windows I had this installed by Boston Truck and Van.
When driving at 70 mph I can hear a slight amount of noise form it if I really listen for it.
One thing that is annoying is the LED to let you know it is in Automatic mode - it is very bright. Some paper and and tape mute the brightness so we can sleep.
And speaking of sleeping....
