Snake Oil or Useful - AirTabs

I saw these mentioned on several forums and with people saying they stabilize the coach in windy conditions. Has any used these? I also own a Class C 2006 Winnebago Aspect 29H on Ford 450 chassis that my son uses.

If they really worked wouldn't they be on the new RV's.

I agree but they get great reviews on the Winnebago forums. On the other hand, our F450 chassis was handled terribly until we upgrade the suspension with Roadmaster Trackbars, Shocks, and steering stabilizers. Seems like those also be on all-new RVs.

I personally, put them in the snake oil category. We had similar things on the planes,
They are called vortex generators and worked very well for the purpose. But they were tested and proven in wind tunnel.
No one explains how these miracle “things” on the RV makes you very stable on the road and adds to your gas mileage? Maybe someone will convince me?
