Figured I'd post my adventure here, got a 98 limited with factory rear locker... which was a huge lifesaver. Went with a guy from a minnesota group here and met with his friends who were all Isuzu club...
I drove 1300 miles there did a bunch of trails and then 1300 miles back 3 days later and no hiccups, freaking awesome.
I only did two trails, Top of the World and A 10 mile wash.
Top of the world i banged my undersides a lot, I had rock sliders from 4x4 innovations hoping to install them out there but got quoted 600 dollars
A ten mile wash, well there were some really skinny paths from which i either had to hug the trees and scratch my rig or fall into the water on the sides, also lots of mud.
All in all If I had rock sliders or a proper lift I probably would've been fine the entire trip.
