Team,
Here is another video of what I learned about roof leaks, and vent covers. I know Mike (MKGuitar) favored the Psiphon 360, but I thought the Camco Cyclone would be easier to install (it was very easy...no pipe cutting); however, I must say, I think the look of the Psiphon is better. The Psiphon costs about $10-$20 more, but doesn't stand out like the Cyclone does. I've never used my Loo for the Poo, so I have never had an issue with odor, so can't really comment there, but I guess now I don't have to worry about that at all.
Enjoy the vid and hope it helps someone else see how easy this job is:

(SORRY THE VIDEO IS A LITTLE LONG...WORKING ON MAKING THEM SHORTER)
Cheers,
