A Harvest Host gave us a "360 Siphon" vent cap, saying it helped a lot with odors.
I'm in the process of replacing the existing cap which, by the way, fell apart as I removed it.
I've never been up on the roof before, and see there's a vent at the very rear - which is the one that fell apart, and another in front of the bathroom vent.
Anyone know which goes to where? I'm betting the rearmost one, which needs a new cap anyway, is the one for the black water but I don't really know.
As an aside, I tried to post a couple photo via Flickr, but this morning I don't seem to have an option that was there before "Flickr.com", which let me dig out embedded jpg links.
The nose knows which is which.

Yep! The rear one passed the smell test!
I'm guessing the front one is for the gray water?
On mine it's rear black, front gray. I assume the same for yours.
