I towed a trailer with about 12,000lbs of stepping stones to my sister's house which was a 20 mile travel. The guys at the quarry laughed because I was loading alongside dump trucks and big gravel trucks. They actually gave me the thumbs up when they realized I made it effortlessly up the 100 yard hill exit. The trip there was uneventful but alot of impressed looks.
I found out about max tow just now.
