Monster Truck is the last truck to be unlocked in Excite Truck. It is one of the best trucks in the game and has the best stats. In general appearance, it is a modified version of the Mongoose and takes the same car body. The only differences are that it runs on monster wheels and has a huge engine on the back. Also, the antenna on the top of the truck was removed and it has three lights in the front instead of two.

The Monster Truck is unlocked by giving each of the other trucks a new paint job by either racing with it ten times or getting three S grades with them. The Monster Truck, however, unlike the other trucks, has only one paint job instead of two. A variant of this truck is called the Crazy Monster Truck, which is unlocked upon getting a S in all race courses in Mirror Mode.
