Ha! I drive like an old man also, but I'm getting between 15-17mpg in town. I get caught in morning and afternoon rush hour everyday. When I don't have to bring my 9 yo son to school and arrive earlier to work, I get 18-19mpg. My family and I just got back from a friend's lake house where the drive was mostly back roads and speeds of about 55mpg, I averaged 21-22mpg round trip. And that's with Ridge Grappler tires.. The truck has about 14,500 miles now.
