Performance Verdict
A strong and reliable gasoline engine, providing ample power (360 Hp) for most hauling and towing tasks. While not matching the diesel's torque, it's a capable workhorse, especially with 4WD.

Pros and Cons:
Pros:
- • Exceptional towing and hauling capabilities, especially with the Duramax diesel.
- • Robust and durable construction built for heavy work.
- • Comfortable interior for a work truck, suitable for long drives.
- • Available 4WD enhances versatility and capability in challenging conditions.
- • Strong resale value, particularly for Duramax models.
Cons:
- • Fuel economy can be poor, especially with the gasoline V8 and under load.
- • Large size can make maneuvering in urban environments challenging.
- • Ride quality can be stiff when unloaded, typical for a heavy-duty truck.
- • Interior design, while functional, might feel dated compared to newer competitors.
- • Higher maintenance costs for the diesel engine compared to gasoline.
