I have an 08 Keystone Fuzion. It has two attic vents on top. Not the plumbing vents. The attic vents have round caps that are about 5" diameter. They screws off and have a 5/16 threaded hole in the bottom. The sun has gotten to them. I have searched and can't find them anywhere. I can't find any brand name on them. Will try Keystone as last resort.
Attic Mushroom Roof Vent Caps....EBay has them for $18.00 too.
