Maybe his tires suck? In all "seriousness" for a second, I'm totally happy with the 3.21. I think the truck has plenty of power, especially considering that I drive not in a hurry everywhere I go. Now, if I was doing significant towing I'd have a different opinion, but just driving the truck day to day, I don't think there's a significant gain for me to have "justified" 3.92's. I mean, I'm not in the habit of cutting people off, but I don't think these trucks have real issues getting up to speed.
