I had a Sidewinder on my Jayco, they work as advertised. You cannot tell any difference towing on the highway between the Sidewinder and a regular pin box. You can feel a little jolt sometimes on a curvy road due to slack in the wedge and side of the hitch. This jolt happens just before the pin box starts to pivot at the torrent, and I could only feel it during a slow speed sharp turn. The hooking up takes a little to get comfortable with, but after a few times becomes natural. I used mine for 4 years with a Reese Signature Series hitch, I liked it. At the time I had the Sidewinder, B&W didn't offer a sliding hitch or I would have never tried it. I pull Gooseneck trailers as well as Fifth Wheel, so the Superglide was not for me at that time. I will say my B&W is a much smoother, easier hitching system, but the Sidewinder does work, and is an option for many.
