I always thought the ultimate offroad rig, was a horse!
That just shows you what you can do if you are from California and have more money than you know what to do with.. so you spend it on something to impress the rest of your buddies..
after watching the video, I still maintain, a horse can get thru those obstacles a lot easier than that rig... and I am sure is a lot cheaper to feed, and you don't have to insure it...
plus if you 'break it' another horse is much easier to find..
