This is something I posted up back in December of last year but it's a cool video just the same. http://toasterjeep.com/index.php?threads/all-new-jeep-renegade-conquers-black-bear-pass.508/ The trail isn't hard - just psychologically challenging.
I'm going with a large group of wrangler guys in the beginning of august to do that same trail. It's totally possible. I've done 4's in my lifted TH with stock tires.
