Who knows why some of the covers fail UV days. Our bedroom vent cover totally disintegrated in the first year, under the Winnebago warranty, but for $10 cost, it was not worth even moving the MH to the dealer.
I added MaxAir covers at that time, just for double protection, glad I did. About 6 or 7 years later, I noticed that the vent cover that I had replaced was in pieces on the screen , but the bed was still protected by the MaxAir cover.
Interesting, the vent covers for the bathroom and overhead bunk are still the 2006 originals. Yes all have the MaxAir covers.
