Seller's Comments

Recent Arrival! 10-Speed Automatic, 4WD, Black Leather. Clean CARFAX. CARFAX One-Owner.

We price our cars to be competitive so there's no haggling to get a good deal. Valley GMC. Where you're a neighbor, not a number.


When the Trailer Is This Big, the Truck Matters Even More

Pulling a big RV over a mountain pass has a way of making you appreciate having the right truck underneath you.

It's not just about power. You want a truck that feels like it was built for serious work, especially when there's a long grade ahead, changing weather, and several thousand pounds following behind you.

This 2025 Sierra 3500HD Denali has just 37,847 miles and pairs its 6.6L Duramax turbodiesel V8 with a 10-speed automatic and 4WD. An exhaust brake, engine block heater, heavy-duty battery, and off-road suspension add to a setup that makes sense for someone who expects their truck to work hard.

But you're still spending a lot of time in the driver's seat. Forge perforated leather, Bose® audio, a power sunroof, and power-retractable assist steps make the Denali feel a long way from a basic work truck.

And with a pre-owned heavy-duty truck, condition matters. This Sierra has been thoroughly safety-inspected by our Valley Service team before being offered for sale.

If you're comparing heavy-duty trucks for an RV, equipment trailer, or serious work, this is the kind of truck worth looking at closely: diesel capability when you need it, Denali comfort when the miles start adding up.
