I have a 2013 Unlimited 4-door, 3" lift and 33's. I drive it from Phoenix to Vegas a few times a year and it drives fine. I have custom bumpers/side rails and it makes me feel good knowing my wife/kid are in something safe (wife drove it through a block wall but that's a whole nother story).
I even tow my 19.5' wake boat with it, no issues.
I'll probably never get rid of it, but you have to understand it's not a "plush" SUV.
