Hi, We have a new 2011 FJ, stock,w/factory hitch and the dunlapped tires. I have read on-line about fins & things and Sevenmile run, but wanted to know your opinion as to what to expect when doing them with a stock FJC. I am a novice, but these were two of the trails I was offered at CM2011 registration. Maybe because I have ATrac and a rear locker. Any recommendations? As rig is new I want to keep it under warranty and budget dictates no OME and big tires, etc.
