when we picked our 2001 cardinal up and I got it home, noticed it had no vent covers. lucky it was always stored indoors. I grabbed some juice containers and cut the bottom out. got some dicor and...
Good catch. The camper is pretty tall and low hanging branches took 3 of the push in replacement caps. I was in a RV dealer and the customer ahead of me was buying a metal vent cover. I didn't know they were out there, so I ended up with one as well. Into its second year on the roof and it has some dings, but it is still there. Metal wasn't much more than plastic, but should last longer. Water getting into tank in freezing climates is not a good thing. Brian
