A guy in the offroad club I'm in went there. This could be a stab in the dark, but did you notice a single cab ranger on 2.5T rocks and 44" boggers? That is him

 

I've never been, but I'd love to go. It's a bit of a drive from here, but I've heard it's well worth it.

Not a chance in hell lol. The amount of trucks and people there is insane. There were only a couple of trucks that I actually paid attention to (The VW Bug, the airplane, etc...) and the Ranger you're describing is just another truck at that place. I probably saw it, but it wouldn't stand out enough to remember.
