The GMC Sierra is all-new for the 2007 model year. It features new exterior styling and new interiors that can be ordered for pure pickup work or for more luxurious family-oriented duties. Those who plan to use their trucks for commuting to work, carrying lots of family members and towing boats, may prefer the SUV-style interior, but pickup truck veterans who use their trucks for work likely will opt for the more driver-oriented pure pickup design.

NewCarTestDrive.com correspondent Larry Edsall test drove GMC Sierras on the desert roads north of Phoenix.
