As a response to the questions about putting a trunk on a Freewheeler. I have put a RickRack on my airwing rack, I have mounted a travel bag on the RickRack so its removable, and the RickRack has a wheeled option with a handle so when you get to where you're going it works like wheeled luggage. I'm also working on how to mount a tour pack to the RickRack so it will also be removable when you dont need to use it.
