I must be missing something because I didn't find anything about this in the "roof" section of the forums.
Anyhow... here are my vents. I'd like to know if any of you have come up with good cheap solutions to covering them. I had a problem evicting lots of wasps this summer, and would like to avoid giving them one more place to put down roots.
Vintage Trailer Supply has these replacement vents: http://www.vintagetrailersupply.com/...VTS-517-2T.jpg
but it seems the flange require one to remove their original base mount. Not sure I want to do that if there's something I can do without needlessly drilling.
So.. if there are vent caps out there that keep rain and wasps out, and don't blow off on the highway... tell us about 'em!
