In all seriousness to the OP. Pay attention to what Jim had to say earlier. I would also add that one must always be prepared for the worst case scenario. ( fire, roll over, getting stuck really bad, catastrophic break down, etc ) Be ready to walk out if you have to. We always carry our back packs in an easy to access compartment. If you have one, fill it up and bring it. I can have ours out and away from the vehicle in about 20 seconds. In the back packs is enough food for 3-4 days, safety kit, extra clothing, a full up water bladder, and a water purifier, along with all the other things one would normally carry in a back pack. So far we have never had to do this, and being anal retentive with our preparing, planning and preventative maintenance, should never have to walk away. I've read previous posts on this subject and the fact of the matter is, you can easily get to some really remote spots even with only a 2-wd vehicle. I'd also recommend paper maps in addition to any navigation aids you might have. So, as Jim said, plan, plan & plan some more.
