It took me 6 months to find my truck in the configuration I wanted: 2x4 LB CC SRW 6sp. Don't listen to those that don't own a ZF6 behind their 7.3. I wanted the manual because 1) it's fun to drive, 2) you get better mileage than the 4r100 trucks, and 3) I didn't want any transmission problems like I had experience in every Ford automatic that I've owned. I didn't buy it to race on the strip. I bought it to haul, tow and get good economy. As it is, with the mods I've done so far in my sig, I easily get 18 city/19mixed/21 hwy; and no I don't have a lie-o-meter.
