Many times I've read this same thing. That someone won't be climbing rocks, so the bronco will be fine. A deep rut in a dirt path will require the same level of articulation as a rock.I watched a lot of Bronco testing footage last year, and TFL's video didn't really surprise me. The Bronco performed just like that in those videos, sometimes teetering on three wheels; but making it.
A lot of the posters on 6G, including myself; admitted that they wouldn't be using their Broncos for crawling any rocks, and that the Wrangler was more suited for that.
Here's a prime example, taken from the original reveal video last year. And within seconds of this clip, the camera person cleverly used a rock on the side of the path to obscure yet another wheel lift and it wasn't climbing a rock. It was a simple rut in a dirt path.
Those posters on 6g are simply making excuses and kidding themselves by saying that they "don't care about rocks anyway".
