The Mack Dual Pack for SnowRunner introduces two new trucks to the game: the Mack TerraPro and the Mack Pinnacle.

Here's a detailed description based on available information:

- Mack TerraPro: This is a Highway-class truck known for its exceptional power-to-weight ratio, allowing players to maximize cargo loads without compromising on power when navigating steep terrains. It comes equipped with a built-in, always-on differential lock, which enhances its performance on challenging terrain. The TerraPro is typically used for concrete pumper and refuse applications in real life but has been adapted for off-road use in the game.

- Mack Pinnacle: Classified as a Heavy Duty truck, the Pinnacle is praised for its superior fuel capacity and switchable differential lock, which provide great range and agility. It's particularly noted for being one of the best Heavy Duty trucks in the game due to these features. The Pinnacle can be fitted with an exclusive log trailer and crane, making it ideal for long-range logging contracts. This truck's design allows for versatility in handling various tasks across different terrains.
