It's the engine of choice if you spend more time hauling heavy payload (like gear, tools, or supplies) in the bed than you do towing massive trailers.
Key Takeaways: Why Choose the TurboMax?

Understanding the Power: Torque vs. Horsepower
When looking at engine specs, the numbers for torque and horsepower can look confusingly similar. Here is the simplest way to think about them when choosing a truck:
Torque (lb-ft)
Think of **Torque** as the brute strength, or the twisting force, the engine creates. It's the muscle that gets heavy things moving from a dead stop and allows you to climb hills without slowing down.
👉 Choose an engine with higher torque (like the 3.0L Duramax) if your priority is **HEAVY TOWING** or frequent hauling of large loads.
Horsepower (HP)
**Horsepower** is the measure of *how fast* that torque can work. It determines your top speed and how quickly you can accelerate or pass traffic at highway speeds.
👉 Choose an engine with higher horsepower (like the 6.2L V8) if your priority is **QUICK ACCELERATION** or driving unloaded on the highway.
