First post! I have really been enjoying this thread. There are so many great ideas in here and it is so nice to see so many people that are afflicted by the same sickness as me.
I took a trip this summer from New Orleans to Victoria BC with a quick stop in Moab to ride the White Rim Trail and then on to Yellowstone (video in signature). Here is the set up I used for the trip. I tried to pair down gear as much as I could but I still took too much (mainly way more tools than I needed). Next trip I am going to lose the top case.
Here it is all set up
Until my tent poles broke and then I found this little guy which will be my new tent for biking as it packs down to about a third the size of the other one.
Dont let the perspective fool you on that picture though. It is only slightly larger than a bivvy.
