DETROIT - Truck Trend magazine says the GMC Sierra 2500HD and Silverado HD are the "Best in Class 2011 Work Truck" and GMC Yukon and Chevrolet Tahoe are judged  "Best in Class 2011 Full-Size SUV."

In its June issue on newsstands Wednesday, Truck Trend picked Sierra and Silverado three-quarter ton trucks over the Ford F-250 and Dodge Ram. Yukon tied with Tahoe, topping the Toyota Sequoia.

Truck Trend lauded the GM heavy duties as pickups "you'll see on construction sites... expected to work hard and take abuse every day." In terms of capability, editors pointed to the Silverado and Sierra RWD regular cab for towing capacity (17,800 lbs.) and payload capacity (4,192 lbs.).

In the full-size SUV category, Truck Trend cited the Yukon and Tahoe's fuel-efficient hybrid offerings, active fuel management, nine-passenger seating and 8,200-pound towing capacity as competitive strengths.

"Despite their size and the hard work demanded of these vehicles, much effort has been put into making full-sizes more fuel-efficient, capable, and comfortable," Truck Trend's editors said.
