At the top of the Calamity Trail are some serious boulders to negotiate. Some of the narrower rigs were able to snake through the tighter spots, but those rigs running fullsize axles usually had to climb over the tops of the rocks. Brian Miller of Raleigh, North Carolina, crawled and romped his way through the rocks in his '01 Nissan Frontier. It helped to have 4:1 Calmini low-range gearing and a Dana 60/GM 14-bolt combo locked up with 5.13:1 gears. Brian would not escape the weekend at Rocky Top with a lot of straight sheetmetal.
