Texas Tech Study "Wing" Details
Does anyone know if the "wing" mod, as accomplished by Texas Tech in their 1988 wind tunnel study, include side closeouts/sails? Or was the mod just an extension of the horizontal roofline (for X inches at Y degrees divergence)? I can visualize the aerodynamic function of aft cab extensions/sails. But it might be really convenient to omit them for a "practical" truck application. TIA.
