I was talking to a friend about towing and flippantly made the comment that the first rule of towing is never forget you are pulling a trailer. It sounded great at the time because I always see trailers with bent and damaged tongues, and tailgates that have been poned and creoled by goosenecks. Now I'm wondering if I was just being a smartass, or if that really could be the first rule of towing. I've never seen a real list of rules for towing. Anyone else have an opinion on this?
