This is the truck that is currently getting me about 18mpg. It's got a very loose auto-tranny with a lockup torque converter that doesn't kick in until about 50mph.
There is a headache rack that sticks above the roof by about 4in, and has a metal screen that is difficult to see in the picture. What difference do you think lowering this below the roof line will make for highway fuel economy at 60mph? I've also considered a grill block to get temps up faster and improve aero.
All of this might be for nothing though, as I may sell it and buy my grandpa's '03 Chevy S10.
