The AT4 trim also enhances off-road performance with features like a lifted suspension and all-terrain tires. These upgrades give the truck more ground clearance and better traction on rough surfaces. The four-wheel-drive system is also a key component, allowing you to tackle challenging terrain with confidence. Performance-wise, the Sierra 3500HD AT4 Dually excels in towing and hauling. The dual rear wheels provide added stability and prevent the truck from swaying when towing heavy loads. The brakes are also beefed up to provide ample stopping power, even when fully loaded.

While it's not exactly sporty, it's certainly more comfortable and refined than many other heavy-duty trucks on the market. The 2024 model year is expected to bring further improvements to the engine and performance. Keep an eye out for potential upgrades to the Duramax diesel, such as increased horsepower and torque, as well as refinements to the Allison transmission.

Potential Downsides

No vehicle is perfect, and the 2024 GMC Sierra 3500HD AT4 Dually has its potential downsides. One of the most significant is its size. This is a big truck, and it can be challenging to maneuver in tight spaces. Parking can be a hassle, and driving in urban areas can be stressful. Another potential downside is the fuel economy. Heavy-duty trucks are not known for their fuel efficiency, and the Sierra 3500HD AT4 Dually is no exception. The Duramax diesel engine offers better fuel economy than the gasoline engine, but it's still not great. You can expect to get around 15-20 mpg on the highway, and much less in the city. The price is also a factor to consider. The Sierra 3500HD AT4 Dually is not a cheap truck, and the AT4 trim adds even more to the cost. If you don't need the off-road capabilities of the AT4, you may be able to save money by opting for a different trim level. The ride quality can also be a bit harsh, especially when the truck is unloaded. The heavy-duty suspension is designed to handle heavy loads, but it can be a bit stiff on rough roads. However, the ride quality improves significantly when the truck is loaded. Finally, the interior, while well-appointed, may not be as luxurious as some other trucks in its class. Some reviewers have criticized the materials and design, noting that they don't quite live up to the truck's price tag. The 2024 model year is expected to address some of these downsides. Keep an eye out for potential improvements to the ride quality, as well as upgrades to the interior materials and design. You can also expect to see new technologies that could improve fuel economy. Overall, the GMC Sierra 3500HD AT4 Dually is a capable and versatile truck, but it's important to be aware of its potential downsides before making a purchase. Consider your needs and priorities, and weigh the pros and cons carefully. If you're looking for a truck that can handle the toughest jobs and don't mind the size, fuel economy, and price, the Sierra 3500HD AT4 Dually may be the right choice for you.
