Sully, Sully, you frighten me, man. ;-)
Actually, the best way to get good gas mileage out of a Raptor is to not buy one. Nobody who knows his own mind buys a 4x4 truck (or any truck, for that matter) if his primary concern is fuel economy. In automotive design everything is a compromise, and there is no such thing as the best of both worlds. Raptors are for performance, and nothing other than performance. Buy it, use it as intented with a silly grin on your face, and never give a second thought to fuel economy. Raptors are not about mpg, have never been about mpg, and will never be about mpg. Think performance, and grin like a madman!
