Freak?....yes......wingless?......yes......fast?......very!.....ditching the side skirts....has crossed my mind! I was thinking of ditching the side skirts and back bumper and getting a roll pan for the rear. Sorry that I don't want everyone on the street to immediately recognize that I have a VIPER truck! The badges and wing are the give-a-ways!
Functionwise.....the wing I don't see being that effective.....you have a big open bed.....then the wing with a gap between that and the tail gate....must create some drag ans that is a place for air to get trapped.
By the way the wing weighs 50 pounds! The weight reduction alone will make you faster!
