Hey Jim, agreed. Most trails, the 3" is adequate. Only been to Moab once, but that place seems pretty wide open (which I love BTW), but what if this was staring you down:I've been to Moab twice since I got my FJ and with Donahoe coilovers in front, Toytec springs/Donahoe shocks in back, Goodyear 305/70/17 MT/R's (which are 34" tires) on factory steel wheels. I've done some of the hardest trails out there without incident. So, to answer your question, a 3" lift and slightly oversized tires will get you through pretty much anything you're likely to encounter in Moab (unless you really go looking).
