A roll cage should be the first part of building a rockcrawler or TRAIL RIG! example, I had a lifted and locked ZJ grand, trail rig, on 35's, would have been great to compete in the stock class of osrc, was once doing the wild west trail in Cedar City, almost rolled a couple times on lads ladder when I decided to take the bypass to avoid a roll and dropped into a stupid little hole and rolled two and a half times knocking out all the windows and caving to roof in to a dangerous level.. Delta's rock coarse is more than a mild trail even in the stock class and if your competeing on it you should have a cage. what a great excuse to hurry and get a cage in your rig you should already have..
that ledge that Troy Hatch rolled off of and landed upside down in his black toyota, would have been serious without a full cage, he was running in the stocker.
