I had the dealer throw mine in with the deal so I didn't have to mount it, but looking at it it does look simple to install. works great with the pass backrest and luggage rack.
Harley gives some vague instructions with the kits but it isn't too hard. The thing that helps the most is having the right tools, if you plan to do stuff you should invest in some good tools, then add as you go. I change out my tour pack when I'm going on long trips.
I did mine on my 05 rk and helped a buddy with his 01 rk it took about an hour each, the wost part was they gave us parts for it seemed 12 different bikes but we figured it out. Good luck
