You should still run a vehicle history report and prioritize a pre-purchase inspection, especially on a heavy-duty truck that may have been used for towing or hauling. Focus on overall condition, signs of hard use, and whether the truck’s equipment works as intended. If you’re shopping a higher-trim example, make sure the luxury and tech features are functioning properly.

Key things to evaluate:

• Trim level: The top Denali Ultimate trim adds a more upscale cabin, standard LED lighting, sequential turn signals, the MultiPro Tailgate, and a six-passenger Crew Cab setup, while lesser trims make do with a smaller 8.0-inch touchscreen.
• Powertrain: The truck uses a 6.6-liter Duramax turbocharged diesel V8 with 470 horsepower and 975 pound-feet of torque, paired with a 10-speed Allison automatic transmission and standard four-wheel drive.
• Safety package: It comes standard with 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 features a 13.4-inch screen, wireless Apple CarPlay and Android Auto, Google built-in, wireless device charging, a 15-inch head-up display, and split-screen navigation.
• 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.
