Between rain drops this past weekend, I installed the Camco Aero-Flo vent covers. As you can see, I chose translucent white for the bathroom and living room where I wanted additional light and an opaque black on the front vent in the bedroom. We sometimes boondock in well lit parking lots when on longer trips. Although this helps with security, having a flood lamp over your bed does make it harder to sleep. Our Arctic Fox had a black out cover that snapped on the inside of the vent - This gave you a choice of ventilation or darkness but not both. Going with the dark vent cover solves this problem for us. In a previous picture I posted, you can see the top of the vent flips up after two captive stainless screws are released - This is not as easy as the MaxxAir with cotter pins, but I should only need access about once or twice a year. This vent has louvers on three sides for circulation but does not use screen material like some of the others. We'll see if debris or insects get caught inside the cover.
