Just why do some of you feel the need to dump on Sleepy idea.:(
Any one with 2 brain cells can see it will make a difference it is just common senses.
Now if sleepy could come up with a idea on what to do with them big Sq. parts of TC right behind passenger door.
They really have to make for a lot of drag.
If you don't thing these things are important why don't you have some one drive your truck roll down your window and stick a 12”x 24” of plywood out the window facing the wind and then move it to a 30 degree angle and you will have your answer.;)
