Owners rate it 4.2/5, a solid signal of long-term satisfaction.

Owner feedback points to a truck that feels dependable in day-to-day use and capable over the long haul, with buyers appreciating its professional-grade character and value. The expert drive data also emphasizes refinement in the powertrain and a transmission that stays composed without hunting for gears. The first scheduled maintenance visit is on the house, which helps lower early ownership friction.

You should still run a history report and verify that the truck’s towing and trailering equipment has been used and maintained properly. A pre-purchase inspection matters most on a heavy-duty truck like this, especially if you plan to tow regularly or want to avoid surprises in the suspension, brakes, or drivetrain. Focus on overall condition, signs of hard use, and whether the truck’s luxury and tech features are functioning as intended.

Key things to evaluate:

• Safety package: Standard equipment includes automatic emergency braking, forward collision warning, lane departure warning, front and rear parking sensors, a surround-view parking camera, pedestrian detection, rear cross-traffic alert, blind-spot monitoring, and a rear-facing cargo bed camera.
• Infotainment: The Denali Ultimate gets a 13.4-inch screen, wireless Apple CarPlay and Android Auto, Google built-in, wireless device charging, a 15-inch head-up display, and a 12-speaker Bose audio system.
• Fuel efficiency: During long highway stints, the diesel returned as much as 21 miles per gallon, while suburban and city driving could dip into the single digits.
