Nice vid Mitch!
I sure felt for those guys struggling, Rocker Knocker is a tricky obstacle that requires most rigs to start where it looks wrong and feels wrong enough to need a fresh pair of BVD's but you walk right up. I have found with less than a 40" tire it does take a single basketball sized rock in that notch to not run the risk of grenading a front axle, even with the best d60 parts.
I do miss the large rock that a couple hit with their rear bumper being next to the notch, that rock is what gave that obstical its name. Love Pritchett Canyon
