Well... you need a stretch of flat road to do coast down A B A testing and I can't t thinK of anything around LA except perhaps up at the Valle Grande. Just warm everything up good grab your stop watch and someone to record the numbers... then do several runs each way with and without. My guess is you want it on. It does not look bad areodynamically to my eyes. As for mods the obvous is an aero shaped cover for the bed but you can't make it too steep or the flow will surely separate and you'll gain nothing. Your truck looks nice and those aren't bad mpg numbers either! Have you got disk brakes on that? If so Hows the pad wear since the racing disc mod?
