A few years ago my father in law asked me to drive him into town to run some errends. I took the wheel of his extremely pampered 80's something Chevy pickup. The grocery store and hardware store went great, all that was left was the post office. I didn't realize that the brackets for his big towing mirrors stuck out way past the mirrors (he had the heads swung in towards the truck) When I pulled up to the mailbox I hooked the mirror bracket on the mailbox and caved the whole door in!
