Not to start a fight, but that is exactly what should be towing these larger, heavier, longer 5ers these days. My original 05 Teton was a 39' stretched custom built with the original owner knowing he was going to carry Harley off the rear of the trailer. He had the wheels of the trailer placed 18 inches towards the rear so that he would be more balanced with the bike loaded. Yes, without the bike he had a 7,000 lb. pin weight which my hdt and hitch could handle! Tracking of the trailer was better, and it cut down on tail swing.
