Get some weight in the bed, it makes a huge difference in traction. With the composite beds, there is not a lot of weight in the back of these trucks. I have an 05 DCLB sport, and with a HC rear, camper shell and around 300 lbs of sandbags nothing really stops me here in NE Illinois.
What would the vehicle requirements for something like Colossal be? Lockers? Winch? Certain tire size? Love the videos, I dream of being able to go someday!
