Factual error: When Tripp enters the garage and we see his truck in progress, he states that the truck will have 425 horsepower. The Hemi pulled out of the Terravex truck is not a 6.4L Hemi (only a 5.7L Hemi) and even if it was a 6.4, they only produced 410 horsepower in the heavy duty trucks. The 5.7L Hemi makes 375 horsepower in the trucks and 390 horsepower in the cars.
Character mistake: When Tripp opens the hood on the Terravex Ram 1500, he states that it has a 6.4L Hemi V8. This statement is wrong, as Ram did not put the 6.4L Hemi into the half ton pickups, only the 3/4 and 1 ton heavy duty trucks.
