Guess it was a good thing that boulder was down there where he landed on top of....looks like he could have rolled a few more times if it wasn't there.
He was lucky he didn't get seriously hurt rolling over like that on that rock.
I can understand the desire to test your vehicle's capabilities. It's not that different from going down a drag strip in a top fuel car. That is what he built his Bronco to do. Nothing wrong with that so long as it is built correctly and you understand the risks going in. Looks like he built it right. He will definitely have something to show the grandkids.
