Hi Bipeflier,
Follow the link I sent.
I agree slowing down works.
Apples and oranges.
Reducing the low pressure area behind a school bus is much different than deflecting air up and over a 5th wheel trailer. There are several different designs for devices to reduce the low pressure air behing over the road trailers but the truck mounted airfoil appears to work if it is within 2' of the trailer, not as well if it is 4' or 5' away.
I stand by the "slow down" as the most effective way to increase fuel mileage right now.
