Like its Silverado cousin, the Sierra is a solid truck in terms of its drivetrain, roomy interior and unique features.  Roomy extended cab models, strong V8 engines, innovative features, slick hybrid electric option.  --According to edmunds.com

Powerful, comfortable, the 2010 GMC Sierra is a prime choice for a full-size pickup.  Smooth and quiet ride, agreeable seats, brawny optional V8s, comprehensive standard safety equipment.  --According to edmunds.com

The new 2007 GMC Yukon is much more refined than the previous truck. Among full-size SUVs, it's a compelling choice.  With its attractive interior with quality materials, Denali's powerful 6.2-liter V8 engine, smooth road manners, and tight turning circle makes this a great family vehicle.

Like almost identical models from Buick and Chevy, the three-row 2012 GMC Acadia offers a winning combination of comfort, features, cargo space and performance in a utility-style package.
