I have the ProPride 3 P for third season now and has been my best purchase after the trailer, simple to install, to use and hook up. No issues so far since I had it. No noise and no "hensley bump" as you referred above. I would not tow a trailer the size I have without it. Sean from ProPride answered all my questions by e-mailed promptly. Before buying, I did a lot of research and read reviews, then why my purchase.
