2020 AT4 with the 6.2, OEM performance exhaust and CAI upgrade. Riding on 33" Nitto TG's
I'm averaging 15.4 at 6500 miles. I do step on it a bit I guess but there are a lot of highway miles on there. I usually put in on cruise at 74.
Surprised to see the 18-20 averages... although I did pass my almost twin truck the other day, he was doing 60 at best, couldn't believe I saw the 6.2 badge on the side. I don't think my truck will even allow me to do less than the speed limit, ?
