Even though my t-case froze on me outside of Barstow, I'm impressed by the gas mileage that I got on the trip to that point. We went over many 9,000+ foot high passes, all of them needing third gear and a few second. Had to use 4WD in the snow in Mesa Verde National Park, was fighting 25+ MPH winds during a lot of the trip and was constantly in and out of third gear climbing over mesas in Arizona and New Mexico. Over roughly 2,400 miles, I averaged 14.6 MPG. Seems pretty good to me, yes?
