I got the passenger bag for the touring bikes from Harley, it's the one that is semi-circle so it fits against the passenger backrest. In that, I put all my clothes, etc. In the trunk, I put my laptop bag, rain suit, and leave the rest empty for whatever else I need specific to the trip. In the tour pack, I put my purse (while riding), and leave that mostly empty for "quick things" i'll need between stops, though lately it's been a catch all for whatever my husband needs me to carry while we're traveling.

I don't have a luggage rack yet on my tour pack, but that is on the list of things to get.
