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 ...
Now if here was a way to move the bug line down so I could reach all of them while staning in the ground,I would have installed it a long time ago.
I read somewhere that the ones that the big rigs use are closer to,and as wide or wider than the trailer. My guess is that for an RVer pulling a fifth wheel trailer,it might look pretty cool,but not really all that usefull.
