This 2019 GMC Sierra 3500HD SLT in Summit White is what happens when luxury puts on work boots and says, “Let’s get to it.” With just 48,628 miles, a clean, no-accident CARFAX, and a build sheet that looks like it was ordered by someone who tows a fifth wheel and enjoys leather seats, this Sierra is equal parts brawn and brains.

Let’s get the big stuff out of the way—yes, it’s got the mighty 6.6L Duramax Diesel V8 under the hood, paired with the bulletproof Allison 6-speed automatic transmission. This isn’t just a truck—it’s a torque-producing, trailer-tugging legend with a reputation that precedes it. If you’ve got something heavy, this Sierra will move it. If you don’t? You’ll wish you did.

The Z71 Off-Road Package adds Rancho shocks, hill descent control, and an underbody shield so you can take the road less traveled—or the job site less paved—without blinking. Plus, the 3.73 rear axle and 220-amp alternator make sure everything runs strong, whether you're towing across the state or just showing off in the Home Depot parking lot.

But don’t let the work ethic fool you—this SLT’s got a soft side, too. Black leather seats, side-impact and head-curtain airbags, 6" chrome assist steps (dealer installed, of course), and a spray-on bedliner to protect your bed from toolboxes, lumber, and your friend Dave who still thinks tailgates are for sitting on.

It’s also prepped for a gooseneck or fifth wheel hitch—because real truck people don’t mess around with “maybe later” towing setups.

And yes—it’s Archibald’s Certified. That means it’s been fully inspected, professionally reconditioned, and comes with a 3-month/3,000-mile limited warranty. We also include a free CARFAX Vehicle History Report so you know this beast is clean inside, outside, and under the hood.

Archibald’s has been the Tri-Cities’ trusted truck headquarters since 2001. We’ve been voted “Best Car Dealer” eight years in a row and featured on Entrepreneur Magazine’s Hot 100 list four times. If it’s heavy-duty, we know it, and we know how to find the best.

So if you’re looking for a serious Sierra that’s been babied more than beat up, loaded with all the right gear, and ready to handle whatever you throw at it—this 3500HD SLT is it. Come grab it before someone else hooks up their fifth wheel and rolls out.

A negotiable documentary service fee of $200.00 may apply to each purchase.
