Can you fit a fully-loaded (complete with tent, sleeping bag, etc.) 60 L backpack on a rear rack, or do you have to take stuff out and rearrange?
If you have to rearrange, how do you deal with it? Do you just completely unpack everything, roll up your backpack, and put it in panniers? That seems like redundant packaging, but much easier than using a lot of bungees for loose odds and ends.
Anybody have any experience with this kind of trip? What I have in mind is riding to a national park, getting a campsite, and maybe do a long hike and some backcountry camping from there. I've done plenty of this by car, but never by bike.
