When travling by myself [09 RKC] I use a 2 piece Tourmaster /roll top bag, my clothing goes in first, I roll everything as it takes up less room, than the sleeping bag on them, my tent fits in the right sadle bag along with a tarp to go under it, and if I pack it right so does the rain gear. Left bag is incidentals, things I want to get to when at a stop, cold riding gear, night light,tool bag, hat to cover the last of my helmet hair, snacks, I try not to put in too much as this is where the things I pick on the ride go. The roll top bag is my grip aka bathroom items, camera, map, bino's, meltable snacks, stays about half full, the tourmaster also has side pockets for other items, if I take a chair, folding of course, it gets tied to the right saddle bag guard rail. When the wife goes we use the Ultra, I get the right saddle bag and the storage pouches in the lowers and she gets the left saddle bag and the tour pack for all her bathroom stuff. No tent no sleeping bag as we always do cabins or hotels when we ride togeather, seems she is allot happier the next day this way. Put all your things next to your bike, pack the bag and see what fits, take old skivvies and toss them after use, no need to carry dirty laundry, but if you do, use the gallon size zip lock baggies and roll the air out when closing. You will find you can carry allot of stuff with you after you have pack'd a few times.
