My least equipped Rocker was a 1983 with 31s and LSD, but also drove a 1990 similarly equipped. I OPENED the Rincon driving the 83, although I did hike from the Tank Trap area down that trip. It just boils down to a couple of epic storms that washed things away. 33's and a locker should be considered min now, but I was happy to have two lockers and 37's in the difficult spots. The trail was never easy, and in a group lesser equipped rigs can make it, but just may not have as much fun.
