Simple answer: nope
Most people that are talking about dents from mirrors or doors are talking about when they take the doors off. If you take off the factory limiting straps before the wiring harness or are not careful about removing the doors, they can swing all the way forward and the mirrors will dent the cowl. You'll see when you get your Jeep.
Edit: damn, beat to the punch
