Wow-- OK I am Brett Wolfe aka Wolfe10.
And yes, I put Air Tabs on the top of the new coach. Have not put them on the sides-- have not found paint to match and have been told by the "boss" not to mess up the paint job.
My take on Air Tabs: Theory is solid-- find a modern air plane that does not use turbulence generators to "fool mother nature". The question IMO is if they help (they do). But no device is going to single-handedly convert a 35' shoe box into an aerodynamic vehicle.
Do they help with side winds/being passed by large trucks-- some. Do they help with MPG-- some. Do they keep the toad a little cleaner-- some.
If you are looking for a miracle cure, not sure there is any such thing. If you want a reasonably priced easy to apply product (assuming you can find Fusion paint to match your coach) consider them-- or not.
