black tank roof
What is your choice for a roof vent. I tried a tornedo. It only lasted a year.

I have had these since I bought the RV and never had a problem.
Same here. Those Cyclone vent caps are supposed to draw the fumes from the tank but it is impossible. The waste tank is a closed system, for fumes to be drawn from the tank it would create a vacuum and that isn't going to happen. The Cyclone is a tax on gullibility.
