My husband and I have done several bike tours and are getting ready for three trips this summer. We have 2 gear bags - 1 for our camping gear and 1 for our clothes. I would highly recommend getting something with wheels. It makes it much easier to shlep your gear from the truck to your camp site. We got ours from REI and I know LLBean has rolling duffles. We also use dry bags for all our clothes. These are long round heavy tube shaped plastic bags that fold over and seal at the open end. We got them at a Bass Pro shop. I think they are really made for boaters. In addition, we picked up some light weight camp stools at Bass Pro that are easy to pack. Hope you have a great trip. We love touring and have met so many great people.
