Ok, some of you may remember that I bought an F250 CC 4x4 auto 3.73 diff(2002). I had hoped to get excellent highway milage but was bitterly dissapointed (10.5 mpg pulling a 2000lb v-nose trailer at 80 mph). After a year and a few months I traded it for an M3 :thumb: and bought a beater truck (94 Mazda B4000). A few things have changed and I am looking at upgrading the truck. I really like the idea of a diesel but only want one that gets good milage at 80mpg. Does a truck like this exist? If I buy again, I'd go 2wd, supercap , shortbed, manual tranny. Should I also consider a 3.5? diff?
