Bottom line: If you're looking for the sportiest sport truck out there, pay the extra $10,000 and get a two-door SRT-10 six-speed. There just isn't any practical way to make a box nearly 19 feet long and six feet tall weighing 5023 pounds feel nimble. However, we should note, this Silverado is reminiscent of the big honkin' Impala SS of yore, in that you can load it up with six people and do smoky burnouts all night long--or at least until the tires melt.
