I am looking to improve aerodynamics on an International 4300 straight truck in hopes of improving driveability and fuel mileage. I think the cab has a fairly aerodynamic design compared to older internationals but it is still just a big rectangle box rolling down the road. So far the truck has no aerodynamic mods. I am thinking of adding a full front fairing first, but have not seen any for sale for straight trucks. Does anyone have any suggestions for mods and any retailers in the mid atlantic/northeast region?
