Well, I’ll have to agree with all who advise against such a journey but with that said – there are a vast number of trails to be had that require no significant modifications at all. The challenge will be to have friends or others that have more capable vehicles to go with you to the more subdued. There are also a large number of bypass routes around gnarlier obstacles where you can drive around first in line (if you can), then park and watch your friends navigate the obstacles. Actually a great way to view experienced drivers and learn the craft.
I highly recommend Trail Damage… follow this link.
TrailDamage.com - All Trails
This web page will give a great deal of information about the trails as well as (and my favorite function) trail head information and trail mapping which can open up in Google Earth. From Google Earth you can fly the course and actually see where the bypasses are (literally seeing actual depressions and tire marks). You can also see the specific obstacles on each course – from there just pop the obstacle name in You Tube and watch endless videos of where to be (front tire placement, to the right of left of a trail section, where and when Moab Bumps need to be applied) etc. For example you might be able to make it up Poison Spider Mesa (a more difficult trail)… this is an “Iffy” proposition, if you stay to the right on Waterfall and to the left of the step up which occurs further up the hill. Again… iffy. Watch the videos and learn. Don’t watch big modified vehicles do it. I’ve seen some pretty stock units go up right down to a Suzuki Samurai.
Granted – the above recommendations are not a panacea for all things Moab, but it will get you close (about 5% closer)(maybe). I’ll probably get FLAMED for making these recommendations but I figured if you are going to do it… you might as well do some sort of research so you’re not going in flat cold.
Have fun, be safe, don’t bounce, bring extra – well…everything LOL. And when you return you must post the obligatory scars received… I’ll view with envy.
