doesnt matter what type of 4 wheel drive it is if you dont know how to use it ;)
I live in Allegany county and wouldnt live without my Jeeps, I have had clients that lived off of dirt roads in the hills and used 4 wheelers and snowmobiles to get home in the winter, I could drive right down (or up) the 4 wheeler paths in my Grand Cherokee.
the 2005 and up JGC's are crap "SUV's", before that they had straight axels and drive trains like trucks, and the grand old 4.0 liter I6 tractor engine or 318 V8, pure junk prissie wagons now :(
My favorite was my 98 JGC limited with a 318 and quadratrac, could smoke all four wheels. My boy buried it to the axels in the swampy mud of our favorite woodchuck field, I rocked it out of the pit in under a minute, would have toasted a late model.
As the saying goes, "its a Jeep thing" :)
