No cheating from me! Don't have a pickup...as to the low side flip, air gets
under the car and...the roof rails and flaps on the roof are to discourage
the air over thep, preventing it from becoming an airfoil. If you look at
an installation, one is straight and one is at an angle. DOn't know about
the trucks...but as to the bed, I would require them on the tonneau also.
Small price to pay and no help for speed.
