The GMC Sierra and the Chevrolet Silverado have been platform siblings for over thirty years now. Showcasing the benefits of platform sharing, these two trucks compete in the same segment, yet offer suitably different value propositions. Historically, the Sierra has always carried a slightly more luxury oriented persona. Now, the Sierra is on its fifth generation and has gained a reputation to be one of the most plush full-size pickup trucks on the planet. However, the Work Truck variant remain on offer, for those who need a truck that can fulfil commercial and agricultural purposes first and foremost. Today, we’ve got a third-generation 2008 GMC Sierra 1500 Work Truck for sale in Vermont, with a relatively light 54,000 original miles under its belt. The truck even comes with a snow plow. So if you’re searching for a relatively modern truck that can handle a rough and tumble life, here’s a great candidate to consider.

GMC and Chevy have been making pickup trucks together for ages. In fact, this stretches way back to the Chevy Task Force series and beyond. When the popular Chevy C/K series debuted in 1960, naturally, GMC would get its own variants. The GMC 1000 was the half-ton variant, equivalent to a Chevy C10 or K10. In terms of mechanicals and styling, the models were basically indistinguishable except for badging, unlike today, where the Chevy Silverado and GMC Sierra have some visual differences. However, this 1966 GMC 1000 Fleetside is definitely a stand-out sort, because it’s a restomod. Packing a potent engine and some neat creature comforts, you could be the next lucky owner of this beauty. But you’d better act fast!
