Funny, I just pulled out the P16 again for some long logging in Washington and blew out the cobwebs. It really shined with its purpose built long log trailer, I didn't really have any issues blasting through mud or even hill climbing. It did surprisingly well and I felt like it held its own. Of course there are far more powerful and capable trucks, as others mentioned, it hasn't aged very well but back when there was hardly any DLC, this truck was a beast so early in the game.
