GM unveils heavy duty Chevrolet, GMC pickups - USA TODAY

General Motors says the heavy-duty versions of its new-generation full-size pickups go on sale first quarter of next year as 2015 models. Those account for about 25% of all Chevrolet Silverado and GMC Sierra sales. Chevrolet and GMC showed the heavy-duty pickups today at the State Fair of Texas. Usually powered by diesel engines, heavy-duty pickups have a broad array of buyers. They range from those who need simple work trucks with more capability than standard-duty -- half-ton -- pickups, to people who tow horse or race car trailers all over the U. S. They want something powerful enough to shrug off nine or 10 tons out... GM gave no prices, but heavy-duty pickups start at about $30,000 for pure work models and can run to $70,000 or more for luxury versions. Source: www.usatoday.com
