I know my truck isn't a quad cab, but in case anyone cares, I drove it across the scales at work the other day, and it was 5280 pounds with me in it. That means the truck is like, 5030 pounds-ish.
Another thing I'm not thrilled with is the shocks. I just got done swapping the rears. I may do the fronts soon, depending on my opinion of the new rears.
