All the stars aligned last night for a new record for me on a single trip (that's not all downhill). I got 30.0 mpg on an 11 mile trip through town. The hills are just right where I can make some power on the uphill stretches then coast for quite a while downhill without loosing much speed. Lot's of green lights and little traffic helped. I realize that for many of you, 30mpg would be reason to hang your head in shame. For a truck that's over 7k empty, over 20' long, and with all the aerodynamics of a sheet of plywood held broadside, that's pretty good. For comparison: 27mpg = previous best trip 25 mpg = best long trip (~ 100 miles of illinois flatness) 23mpg = best tank 19mpg = best tank with previous trucks (both half ton, 2wd, reg cab with 4.XL gas engines) 10mpg = what my dad gets around town with his slightly smaller work truck w/ a gas motor and auto.
