Most Popular Roof Vent for 2018 Thor ACE Motorhome

So I give it five stars, but I'm not commenting on durability with that rating. I mounted this to cover a standard 14" square vent in an enclosed car trailer that we camp in sometimes. Installs in about two minutes with just a screwdriver, and it fits over the opening just fine. It is not a blackout curtain, but it cuts WAY down on the light coming through so I think it will help if trying to sleep past sunrise. It isn't heavily built, and hopefully the UV doesn't make the mounting clips brittle. If not, I'm happy for my purposes. It definitely blocks light, so I think it will block some heat also, but that was not my primary reason for buying. Very satisfied overall if it holds up.

This is is the fourth shade I’ve gotten for my RV- now all skylights are covered. They work great and help to cut down on heat from the sun and light at night

My MaxxFan would only work on high speed (that let me know that the motor was still good). Changed the circuit board and now everything is to good in my world (until the next thing breaks)

This circuit board installed easily and works better than the original. The program remembers the selected fan speed when you turn it off, so you don't have to start at low and step up to high speed. Very satisfied.
