This is a base in-game GMC Sierra 1500 converted into a Monster Truck by the one and only KickFlip360 of Kc's 4x4 Evolution 2 site with help from SuperMotoXL, Some parts on the truck are by unknown authors and likely won't ever be know, Truck appears in Career under GMC and in custom class under Free Roam. Truck is not by me and I do not take credit for it either, Reuploading all vehicles possible from Kc's now closed website to make sure they are not lost.
I'm really glad they haven't forgotten about this game yet, this game marked part of my childhood and I still play it !!! Keep it up, give other opportunities !!
