Just finished watching the videos myself - this is very impressive. What was just amazing was the Escalator video in the 2nd half where the guy literally backed all the way up escalator part time on 3 wheels.
Damn.
I'd like to point out one thing I haven't seen discussed relative to this durability testing itself: the heat.
Today (8/10) it was 104 deg F in Moab. HOT AF!
It's not coincidence they're doing this in Moab now on some of the hottest days of the year. Heat wreaks havoc on cooling systems (and everything else) while wheeling. I've experienced this in Moab myself...
Looks like this one lost a rock slider and they threw on a spare meant for a two door. Maybe this prototype just never had them in the first place and these are the parts they had on hand? I hope they didn't actually break one.
