Near the beginning of the movie when Jack decides to take the job, he gets in the black Peterbilt, however the inside of the truck isn't a Peterbilt, BECAUSE first of all when it shows Jack putting his foot on the clutch, it's a hanging clutch, meaning it isn't coming from the floor. All Peterbilts have clutches coming out of the floor. Secondly, when Jack goes to start the big rig he turns the key and the truck starts right up, that can't be possible because all Peterbilts have a push start button also. While Jack may be starting a big truck, it isn't the black Peterbilt he drives throughout the movie, the inside looks more like an International. Thanks - Caley.
