Howdy, here is the result of the Popular Mechanics in DEC '07
Full disclosure: We asked GMC for a truck with dual rear wheels to match the others. But neither GMC nor Chevy could supply one. Duallys are heavier by about 250 pounds and typically carry a stiffer suspension. That said, GMC’s 365-hp Duramax diesel was so strong, and the fuel economy so much better, that even with the handicap of “training wheels” the results would likely have been much the same. The leather-lined $50,834 GMC, the least expensive of the group, was clearly the hot rod. It stormed to 60 mph almost 2 seconds quicker than the Dodge and almost 4 seconds quicker than the Ford. One tester proclaimed it could smoke the rear tires even with the trailer’s 1100-pound tongue weight pressing down on the rear suspension. That, friends, is a seriously strong motor. Yet the GMC was equipped with highway-oriented 3.73:1 axle gears so it returned 18.26 mpg on our test loop—a solid 5 mpg more than the Dodge and 7 mpg more than the Ford. Better still, when hitched to our trailer and excavator, the GMC returned almost 2 mpg better than the Dodge and 3 mpg better than the Ford. Over the working life of a truck, this matters. But winning performance tests doesn’t automatically get you the gold medal.
Away from our test equipment, the GMC was the smoothest and most carlike. It was the only 4x4 here with an independent front suspension, which helped the handling, too. You get a choice of two completely different dashboards—one traditionally trucky and the other more luxurious. Ours was the latter, and testers liked the layout. It’s also worth noting that the Sierra had the best air-conditioning system—by far. After long days on the road, we were less fatigued behind the wheel of this truck. In short, the GMC had the speed, efficiency, comfort and function we look for in a big pickup—and that makes it our winner.

You supposedly just read 2 previous responses, Frame cracking and not comfortable with pulling in mountains. Use this as a guide would be my suggestion.
