When we purchased our used Flagstaff, it had the sidewinder hitch installed. It was my first experience with one. It steers awesome and I can turn 90 degrees in my GMC crew cab short box. You can also load the bed of the truck all the way up without worrying about the hitch swinging into stuff as it swivels at the trailer instead. The only con I have with it was getting used to doing down steep grades with curves while braking and it sticking for a second before rotating. I think I may have caused this sticking by spraying slide lube in it which may have broken down the lithium grease. I got the diagram from the company on how to tear it apart and lube the plates so I'm hoping that will fix that problem. Otherwise, I'm very happy with it.
