Vent mod - do these work?
Saw these posted in another thread... Xtreme Vents Do these actually make a difference? My wife is VERY sensitive to the odors of the bathroom, so anything that helps is worth a look!

Yes they work. We have one on the black and grey water pipes on the roof. Before that I could smell the black tank after traveling. Not when stationary. So figured it wasn't venting.
