This past weekend some Harley friends and I rode west for a get together. I told the group about my research on the Spyder and how one of the things I was impressed with was being able to get a factory warranty on the Spyder, the wiring harness, the hitch AND the trailer. One guy spoke up and said he heard the only way to get that warranty was to purchase all of the above at one time as a package. Can anyone confirm or deny?
