Teasing a little. I am 38 but my bad back has me feeling old before my time.

That mileage is not normal obviously...over 65,000 miles per year (or nearly 200 mils per day 365 days a year). I think you might be waiting a bit longer to get the feedback you want. Nice to be young.

As far as MPG on 6.1L I think a lot will depend on your foot. I would guess 17-20 maybe. Surprised that they would not offer those engine systems that cut back the number of cylinders firing on highway driving. Maybe not be something that will convert a fence sitter into a buyer though. My brother in law has it on his Honda Odyssey and they get about 30MPG on highway driving.
