About the GMC Sierra 2500
Since Dodge released its first D/W series pickup trucks in 1980, the company has taken the truck industry by storm. RAM trucks consistently battle for top sales with the Ford F-Series and Chevrolet Silverado—together, the three automakers make up the “Big Three” domestic brands.
RAM has some prestige that the other brands don’t, however. In the mid-nineties, the company was the first to cram a high-performance diesel engine into one of its pickups with the release of the 5.9L, 12V-Cummins-powered 1989 Dodge Ram D250. Since then, RAM has been at the forefront of HD truck innovation. After five generations and nearly three decades, the company and model show no signs of slowing down.
