I have no experience with that type of vent, nor of the others designed for
the same purpose, but I've been very happy with my cheap, simple, solution:
Just mount a 1-1/2" PVC Tee with the straight-thru portion aligned
longitudinally. The airflow through the horizontal section at road speed
creates a vacuum in the vertical vent tube. When stopped, the vent tube is
still covered for protection from rainfall.
Related old-timers story: When we bought our new '97 Safari, we had
persistent problems with septic odors in the big bathroom. I finally
ripped out the right rear corner "box" in the bathroom closet which
concealed the black water tank vent. I found that the 3 joints in that
pipe had NO cement on them. Properly glueing them together (and reducing
the box size by 2/3 to recover closet space) fixed that problem.
When I later recited that tale to a fellow Safari owner in the waiting room
at the factory service center, he was totally unimpressed. "On mine, they
didn't bother to cut the hole in the roof; just cut the pipe off..."
Don't think buying a new SOB will insulate you from having to work on your
coach! :-)
