- • Exceptional towing and hauling capabilities with both V8 engines.
- • Powerful Duramax diesel offers class-leading torque and efficiency under load.
- • Spacious and well-appointed interior for a heavy-duty truck.
- • Robust build quality and strong chassis for demanding work.
- • Advanced trailering technology enhances safety and ease of use.
Cons:
- • Large size can make maneuvering in urban environments challenging.
- • Fuel economy, especially with the gasoline V8, is a significant consideration.
- • Ride quality can be firm, as expected from a heavy-duty truck.
- • High purchase price and ongoing operational costs.
- • Limited customization options compared to some competitors.
