We camped next to a guy last week who was towing with one of those big 16 passenger type vans. He had a big TT (at least 26 ft) and said that old van pulled it great. He's been using it for years and was very happy with it. He called it his "Chester the Molester" van. We were in the north Georgia mountains, so he's got experience on some big hills.
