I have a friend who recently bought the new Prodigy, and had the opportunity to drive my Fifth wheel around the block using his truck (85 chevy dually). I was pretty impressed with how smooth it was, but it wasn't as smooth as my Jordan, expecially at lower speeds. Nothing scientific here, and I imagine it can depend on alot of variables, including truck/trailer weights and how they are set up and adjusted. I would think that the two are equally reliable. I really like my Jordan though, much better than my previous drawtite.
