So, I went to my local RV dealer/parts place and seems that these are only available via the RV Manufacture. They aorderd then straight from Forest River and they actually cost lest that the Camco Velcro type Vents (without shipping) $8 and change. Well, I guess if you count the shipping of $11 it might be close to Camco.
