Dave found this video of the first 10 minutes inside the 8131 truck driven by Robby Woolworth - which so happens to be my wife's cousin's husband driving.
The experience as recorded on the video is exactly what it was like being passenger in the XterraRacer. It was right around the 10 minute mark that we lost the 4x4.
Its hard to tell but this truck (and the X) spent alot of time in the air.
ENJOY!
Here's the video:
