Can anyone testify about a Fibro Concept trailer, good or bad. I'm riding a 14 RTL and found a 04 Fibro Concept trailer for sale on Craigslist. I really like the look of the trailer but need advise, anyone ever pulled one with a Spyder? A friend mentioned that a friend of theirs pulled one behind a Goldwing and had major vibrations around 60 mph. Any info is greatly appreciated.
