I used to install Cyclone vents on my previous RV's. But, when I installed one on the Vegas I found that turbulence was created at hwy. speeds most likely from the vent cover or shower dome. This caused the rotating top of the Cyclone to jump up and down making a noticeable sound and eventually nearly destroying the bearing part of it. I now have a static Siphon Roof Vent Cap which is doing fine. YMMV if they changed the roof vents on later models.
