I saw part of a program about Semi Driver life stiles.One of the Advertisers was Air Tab.The subject comes up infrequently but nothing decisively or ancedotaly has determined it a great idea. I understand the physics and aerodynamics and practicality if the design is sufficient. Anyone use them here o know of something about them?

Debate has gone on for years. I do believe they help to keep the rear of your unit clean but if they were truly economically worthwhile we would see them on every semi out there. They travel far more miles than the average RVer. JMO

Yep, it has been debated on here before. Pretty much it comes down to the number of miles you need travel to get your money back. Very few RV'ers travel enough miles.As to why you don't see them on semi's, there are other ways to make bigger gains like the fold out tailwind additions and the skirting you are now seeing under the sides of the trailers.

My RV handled very well but cross winds and passing trucks upset it quite a bit,after installing Air Tabs,cross winds and trucks are no longer a problem as it once was.They also keep the rear of the RV cleaner,as to the help in MPG I saw very little difference.

I didn't notice any improvement in mileage but they did improve the handling in crosswinds and since I traveled a lot in the Great Plains, where wind is always an issue, I wouldn't be without my AirTabs. Basically since they cost less than a tank of gas, the improvement in handling at highway speeds, is enough for me.

If I had a two gallon tank I might give them a try. :B
