Has anyone added A Fulton Swing Away hinge to their trailer?

If so, what was the experience?

Yes. I added the bolt-on version when I converted a sailboat trailer to a kayak trailer in 2018 and extended the tongue about 3’ for my longer boats. Never had an issue with it and have used the folding feature quite a bit over the years.

You can see it in this photo (middle boats are just stored on the trailer in this pic, not hauled that way):
