Unfortunately here in AZ the mesquite and other brush and trees will give you pinstripes. On my 2019 I tried really, really hard to not get them. on my 2020 I just enjoyed the trails and did not worry about it. On wider trails, you will be ok and what you do get will buff out pf the paint. however, the hardtop and fenders and mirrors will show it and wont buff out. Just too much here that can scrape the sides, and trails that are narrow to avoid them. just go into it expecting them, and you will enjoy your trails much more.
Another area to watch is the window seal trim. when it is really hot out that is known to scratch. I am actually ordering painted fenders this time as they actually seem harder and dont gouge as bad as the softer blaxk molded fenders. It seems it doesn't take much in the hot sun to put a decent scrape in the fenders. the mirrors were not as bad, and then hardtop next. if you use 303 on the hardtop it does a good job to hide the lighter ones. on the body I really dont bother trying to fix. I only buffed it out before selling as the tub etc. is thin and im not sure how many times it will take a deep buffing before the clear is shot. I do trim some trails still, but not like I used to. (some trails practically take 4-low to push through the brush etc. it feels like) I still cringe on those, but its because im afraid of a body crease, not pinstripes. (I creased my Grand Cherokee Trailhawk down the entire passenger side like this)
