First semi-long trip in the truck this weekend. 225 miles round trip that went from 5,000 to 11,000 miles above sea level. Mostly highway driving, but some stop and go. Computer showed an average of 20.6 mpg.
Mileage definitely suffers chugging up the moutain passes, but it's great to see the improvment coming down the other side in V4.
5.3 Crew Cab SLT 3.42 with BakFlip Tonneau and 20'' wheels. Only 600 on the odometer.
