Some of the comments here are disturbing. People saying things like this guy was driving so its completely his fault is what got the country into this sue happy mess that shuts down anything fun start with. Dont get me wrong if he was falling down sloppy drunk its definately his fault, but it doesnt sound like anyone can confirm this so far. I completely agree that if he was that drunk he is liable.
But the key word here is "accident". comments like "he was driving it was his fault" opens everyone up to liability that could end this sport alltogether. I doubt many on this forum have managed to go their entire wheeling career without a rollover. Now imagine a tree branch, rock, unsecured tool, etc etc injured your passenger during that rollover. would the "he was driving its his fault" still apply. How about your rig knocking a rock loose at the top of a hill that rolls down and injurs a bystander? Does "he was driving its his fault" still apply to that accident too?
I definately dont condone drinking and wheeling, the sport is dangerous enough as it is. But saying this is 100% this guy's fault because he was driving is crazy. I'm pretty sure I'm not the only one that has ever rolled an offroad rig stone cold sober, it does happen. The truth is this is an accident and all the circumstances combined contributed to it. Everyone that wheels at Stony should know its dangerous, they signed a piece of paper at checkin saying they were aware.
