MaxAir (sic?) cover kept the rain out so I never noticed this probably for several months.
The guys are right on,,, take old lid with you,,, it took me 3 trips,,, and I thought I knew which one I needed !!! Lucky RV dealer is very close,,, and they let me take one home to try !!! Dealer was sure he knew which one I needed,,, he did not !!! I did put 2 or 3 layers of Fusion white paint on mine before I replaced it,,, ours was bath fan vent cover !!!
Old one was 3 maybe 4 years old,,, it was the thickness of paper,,,
cooked by the sun !!!
