I'm Big Dave and I try to get the best possible MPG out of a Ford F-350 pickup truck. So far, I've gotten 30% better than when it was new.
I don't think 26 MPG out of a 8,000 lb truck is bad but I believe I can do better.

4x2, 6 speed manual
Regeared to 3.08:1
4 inch suspension slam
Aero mods: "Fastback" fairing and rugged air dam and side skirts
Stock MPG: 19
Summer MPG: 27.0
Winter MPG: 24
I'm guessing it is not a dually? Lowered? 26mpg is not the overall average?
I am into diesels myself...Jeep Liberty CRD...all stop n' go for the most part and getting 22mpg with very few highway miles. When I do hit the highway I can get 30+ holding 64mph or so. I put a taller tires on to "regear" a bit...but I need to do a Suncoast Torque Converter to get rid of any "slipping".
