ehh, that's why they're "break-aways" you can hit a tree with those things and they just fold in, although my brother tested hitting a 4x4 post at highway speeds with his tow mirror in his duramax, lets just say post=1, mirror=0 lol.I love the Towing Mirrors. I've been thinking about getting some myself and fitting them on my truck. My only thought is when I'm trail ridding, they might stick out way to far.
