Truck Airfoil

[The_Works]

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 5th wheel? Thanks for your thoughts and input.

Think about it - car mfg's are always looking for ways to improve performance and or economy.

Because cars aren't carrying a big wall that's higher than they are behind them? That argument doesn't make sense to me.

But, to the OP- I haven't heard that they are worth the money. The improvement is incredibly negligible and not worthwhile for the normal RV user.
