Sometimes after towing our trailer I will notice during setup at the campsite the smell of waste tank odors. I think what happens is with all the rocking and rolling the trailer endures while on the road, the water in the plumbing P-traps gets washed away and tank odors can seep inside the rig.
I believe a simple upgrade to the standard RV roof top waste tank vent covers will be a solution to these nasty odors. A product called a 360 Siphon looks to be just the ticket.
I’ve seen some rigs with a spinning fan sort of waste tank fume extractor but really like the fact that the 360 Siphon has no moving parts and sits nice and flat with a dome top. With its low profile, alien space ship looking design it creates an air vortex that sucks the fumes up and out of the waste tank.
