Review on 🏞️ Camco 45651 Insulated Dual Vent Cover - White, 14" x 14" - Premium Quality Solution for Improved Ventilation Efficiency" by Sean Zamora

They are not worth it. In reviews, this product sounded like the best since slide-outs. You are not. Perhaps most of the 5 star reviews have been bought. I still had to hold the pillows because two of the three were deformed. Deformed lids allow air to escape. Cheap mounts/clamps are not as polar white as the cover. Universal screws do not have a button head and are not colored as they should be. However, you can still use the original painted pan head screws if you only use one of the brackets/clamps. As a result, there is no possibility of ventilation. The seller is aware of these defects. That's why they only used one photo. Judging by the description, I thought this vent cover was open. Instead you slide it and put it back on the second brackets/clamps (they are folded) to create an air gap. This does not work for me. I have DRV Houston. Of the three vents I can only get to the one in the main bathroom. I was hoping that the vent cover could be opened with a telescopic pole. Because they don't open up, provide no insulation, block heat/air leaks, or look better than cheaper, less obtrusive insulation pads, they're useless to me. I had to open them before the return window closed. The pillows are much better. For them you have to go back to the drawing board. Brackets of different colors destroy the rigor, they are designed to improve the quality of the pillows. Happy camping. Hooray! Cameron
