The new 2007 GMC Sierra HD lineup has the segment-best gross combined weight rating of up to 18,500 pounds, and the segment-best trailer weight rating of 13,000 pounds--both important numbers considering their intended duty as heavy haulers and commercial rigs. And with extensive new noise-reduction measures, it has one of the quietest interiors among heavy-duty trucks.
