Something to keep in mind, Gross vehicle weight (load capacity) of a Tri-Glide is 1700 pounds. Wet weight is 1191 pounds. That leaves about 500 pounds capacity for you, passenger, and anything else. We have members here where Mommy and Daddy are pushing that weight limit, not counting the trailer and all the goodies in it. (I being one of them) Probably one of the reasons Harley will question the warranty when there is a hitch bolted on.
Good Luck
