That would be the Esteemed Mr. Hagen who played a little too hard with one of his creations.
The axle shaft snapped off right at the end of the axle housing carrying away the wheel and - I suspect - the brake system.
I looked at it up close in camp (sorry I forgot to take a pic). The axle was broken off just inside of the brake mounting flange and the flange itself was bent up a bit.
This truck drew lots of attention throughout the event! Unique body and drivetrain work!
