III (GMT900) Extended Cab Long Box Overview:
GMC Sierra 3500HD (III (GMT900) Extended Cab Long Box). With 515 Nm of torque, it offers ample pulling power. At around 2674 kg, it’s on the heavier side.

Performance Verdict

- • Exceptional towing and hauling capabilities, especially with Duramax diesel.
- • Robust and durable chassis built for heavy-duty work.
- • Comfortable interior for a work truck, improved over previous generations.
- • Wide range of configurations (4WD/2WD, SRW/DRW) to suit specific needs.
Cons:
- • Fuel economy is poor for gasoline models, and still significant for diesel.
- • Large size can make maneuvering in urban environments challenging.
- • Ride quality can be stiff when unloaded, typical for heavy-duty trucks.
- • Higher maintenance costs for diesel engines compared to gasoline.
