The Sierra 3500HD Denali Ultimate combines purposeful engineering with luxury appointments. The Duramax turbodiesel provides substantial torque for towing and hauling while maintaining efficiency on the highway. The ProGrade Trailering System transforms towing into a managed experience, with integrated cameras and tire pressure monitoring that keep you informed during every mile. Advanced technologies like Ultrasonic Park Assist, Automatic Emergency Braking, and Lane Departure Warning work seamlessly to support your driving, whether navigating tight parking areas or open roads.
The cabin presents a thoroughly refined environment. Heated and ventilated front seats with lumbar adjustment ensure comfort across seasons, while the heated steering wheel adds welcome warmth on cold mornings. The Bose audio system delivers quality sound, and wireless phone projection means your essential apps remain accessible without distraction. With nearly every convenience feature thoughtfully integratedâ"from the keyless start to the remote vehicle starter to the garage door transmitterâ"daily operation becomes genuinely effortless.
Off-road capability meets on-road composure through the X31 Off-Road Package and Active Transfer Case. Hill Descent Control assists on challenging terrain, while the suspension geometry maintains predictable handling on conventional roads. The 20-inch ultra-bright machined aluminum wheels provide both visual presence and functional performance.
At just 5,901 miles, this Sierra 3500HD remains virtually new with factory warranty protection intact. The combination of premium content, exceptional low mileage, and the reliability inherent to the Duramax platform makes this truck ready to serve for years to come.

Dealer Notes
MSRP refers to the Manufacturer’s Suggested Retail Price of the vehicle. Prices do not include tax, tag, title, registration, dealer-installed accessories, or dealer-provided benefits. Additional fees include a $1195 pre-delivery service fee, a $149 Private Tag Agency Fee, and a $499 Electronic Registration Filing Fee (this charge reflects costs and profit to the dealer for services such as inspecting, cleaning, and adjusting new and used vehicles, as well as preparing documentation related to the sale). Please consult your dealer for the actual price and complete details. Vehicles shown may include optional equipment at an additional cost. All prices, specifications, and availability are subject to change without notice.
Online pricing may differ from dealer pricing due to supply-chain constraints. All pricing presented is non-binding and does not constitute an offer. For the most accurate and current pricing, please contact your dealer directly. All incentives and discounts are calculated based on South Florida zip codes.
Pricing includes all applicable manufacturer incentives and may not be combined with other exclusive offers. Advertised prices apply only to in-stock units and include all eligible dealer and manufacturer discounts and incentives. Certain offers and incentives may require financing through the manufacturer’s captive lender and are subject to approved credit. Although every effort is made to ensure accuracy, the dealership is not responsible for errors or omissions on this site. A copy of the advertisement must be presented at the time of purchase to receive any special or advertised pricing. Prior sales are excluded. Due to ongoing supply-chain challenges and limited inventory, vehicles may be subject to additional market adjustments based on production schedules, availability, and market conditions.
Payload and towing ratings are maximum estimates. Additional options, equipment, passengers, and cargo may reduce actual payload or towing capacity. Please see your dealer for complete details.
