Conquering the Rocker Knocker on Pritchett Canyon in Moab is not an easy task. To simply crawl up this obstacle in a short-wheelbase vehicle is pretty much unheard of. Between the capability of Kevin Hawkins' Jeep and his driving skill, it happened, but in no small part due to the special soft-compound Interco TrXus MTs. Ironically, Walker Evans, whose name is on those nice bead-lock wheels, can't always make it up the Rocker Knocker without making numerous attempts. On White Knuckle Hill, Kevin's special TrXus tires went right up, while Walker's vehicle didn't, at all.
