dredging up the dead again.
From the first time I saw the airtabs and saw their effect on tractor/trailer rigs, I was intrigued. Then I saw people trying to use them on small cars, and also saw what others have mentioned that they do appear to smooth the airflow but do not appear to contribute significantly to MPG.
What is the consensus on using them on a full-size truck such as mine?
When I first bought my truck, I considered adding them along the roof line, down the side of the cab where it sticks up above the bed line, and possibly again near the rear corners of the bed. Now that I have a tonneau, that consideration has extended to include along the back edge of the tonneau.
That's a lot of airtabs (@ ~$2.50/ea) to buy and stick on just to "test".
