I can't answer your question on build differences but I can say:
Big difference is traction. Roots, trees down offer no traction at all, worst thing in the middle of a rock garden is a downed tree that is now an obstacle. I have cussed every downed tree I came across (even small 6" dia trees). Clay that clogs your tires between obstacles, rocks with no traction with a film of wet clay. It creates a very unique "bump", as we like to say hit it with a little enthusiasm. Steep rock slabs are like ice, even when dry. Clay access roads that have had buggies with 40+ tires rut them out and now a TJ with 35s has no hope at all to make it through.
I was just in Harlan Ky and one trail had a spring at the top which kept the trail wet all the time!
Going out west makes us all cocky when we come back!
