I just drove 60 miles today with the RV on a route I have often travelled. This year, I have done this trip 6 times (without AirTabs until today).

The route is a combination of about 30mi of freeway driving (with the cruise control set to 60 mph), and 30 miles of secondary highways, a few hills, and a few towns (cross streets, stop signs, etc), with 25, 35, and 55mph speed limits.

Before the AirTabs, I was averaging 8.5mpg on the scangauge on this route. Today I averaged 9.2mpg.

Now this was the initial test so I don't know if it will hold up over time or not, so we'll see how it averages over time.

With semis passing in the opposite direction at highway speeds, sometimes I felt no push, but a few times I still felt a push, but it was greatly diminished. But this push has never really been bad anyway. All I can say is it seems to have been reduced.

I have not yet towed the car with the tabs on, so I don't know how much cleaner it will be (if at all) or what the gas mileage changes will be.

I guess at this point all I can say is that I am encouraged by the initial results. By nature, I am a bit skeptical, but I believe there is some sound principles behind the phenomenon.

So my initial conclusion is there is indeed something going on here... but how much of an improvement it makes is still to be determined.
