Rocker Knockeris another difficult climb up Prittchet Canyon past the Waterfall. Longer wheelbases will excel on the left. Shorter wheelbase rigs can start near the center, creep up over the first hump, and crabwalk over to the left. If you do this correctly you can drive up the obstacle, but it ain’t easy—even for well-built Jeeps. Be ready to winch. There are other lines to the right, but they take power, commitment, and there’s a high price for failure.
