And please not let this get into a truck pissing contest.
I doubt any other truck mentioned in this thread can outrun that tundra. Those things are FAST.
I don't like them at all, but that's a hell of a motor in that truck.
Just realize that if gas mileage is a major concern, you may want to go a different route such as a smaller half ton with a smaller v-8.
My buddy averages something like 14.5mpg with his riding around town. It pulls like a mother fricker though.
