You're thinking of bump steer. DW is caster or maybe just roasted bushings/TREs/SREs
As for the thread topic: it's the last not-a-3/4-ton-truck with solid axles front and rear. And you never realize how little sheetmetal they have until you stand next to one and think about it. Both of these are HUGE advantages for rockcrawling.
I really, really wish Ford had gone SFA on the new Bronco. The Wrangler needs a blow-for-blow competitor.
That said, Wranglers are the most easily modified vehicles and thus require little skill or vision. It's like buying a paint-by-numbers kit and then claiming you're an artist. And yes, I have a JL on 37s. And yes, that does make me a lame poseur, too.
