Unlock Champ Trucks
To unlock the Champ Trucks, begin one season on any difficulty with any truck. Once you finish the first season(of 3), the game will tell you that you unlocked the Champ version of the truck you used, and will show you the truck. It's basically just the same truck with gold paint on the strut bars, chassis frame etc., a gold Monster Jam plaque on the front bumper, a Monster Jam flag on the back, and the stats that you finished the season with(horsepower, acceleration etc.).
