Does the cost of installing a airfoil on the cab roof of my truck offset any increase in gas mileage because of the aerodynamics? Does the airfoil effect handling of the truck while hauling a 35 foot ...

I'm not an engineer, but I do know the airfoil is used as a down force on race cars to help hold the car down on the track. I have to believe just because it is now mounted to a truck the same dynamics are now still in place. In essence it makes you move more weight with the down force if your moving at speed, my opinion. In talking to many folks we have seen over the years with those foils most have said no change in fuel usage, just helps keep the front of the 5'er cleaner from bugs, the foil is catching the bugs the 5'er would have.
