Tour Pack (unless you ride a dresser) - High quality, waterproof with reinforced stitching. There are several brands to choose from. Ours is made by SAC and is excellent. It is fully plastic lined, with a double fold over panel, to keep water out. And it's HUGE! If you're looking for a good tour pack, click on the J&P Cycles button, on the left, and search for luggage or tour packs.
Matches - Put a spare pack in some type of waterproof container and store them someplace on the bike that you can always get to.
Toilet Paper -You can purchase mini camping rolls at Target, K-Mart and pretty much any sporting goods store. Bring way more than you need and remind your camping buddies to bring their own cuz you ain't loaning yours out. Keep your toilet paper dry by storing in a zip lock bag and don't forget to keep a roll handy for those middle of the night visits to the port-o-potties.
Self-Charging Flashlight - Maybe not an essential, but these things are pretty damn handy. Compact and rugged, all you have to do is shake them for 5-10 minutes and the little magnet and coil generates enough juice to put a small charge in the battery and keep the bulb light long enough to get you through that port-o-potty we just got done talking about.
Bed Roll or Sleeping Bag - Depending on how cold it gets where you are camping will determine what type of sleeping bag you will need. We have opted out of using sleeping bags and have made up bed rolls using a single wool US Army blanket and a Coleman fleece blanket, for each bed roll. Roll them up and wrap a bungee cord around them. Bed rolls are smaller than sleeping bags and easier to manage. We added a Coleman camping pillow to the mix and it's a perfect setup
Toothbrush & Tooth Paste - This one's kinda obvious
Bottle of Water - It's a good rule of thumb to never roll w/o a bottle of water on the bike. Hunger you can put aside, but getting dehydrated is a killer.
Couple of Large Trash Bags - A life saver if the weather turns sour on you. Not only can trash bags be used to wrap your gear up in but, in a pinch, they make a great rain poncho and can also be used to make a "lean to" for shelter from the rain.
Duct Tape - You can fix ANYTHING with a roll of duct tape.
Snacks - Always a good idea to have some jerky or a couple energy bars stashed on the bike or in your jacket pocket. You never know how long you might be stranded on the side of the road, if the old girl lets you down, or if you might need a midnight snack, at the rally.
Medicine Kit - It's always good to carry a few basic medical needs with you, just in case. We made our own medi-kit, using one of those small make-up pouches you get at about any department store. In it we have put the following items: Tylenol and Motrin (we combined in the same small pill container, we can tell the difference); Amodium AD (this is a must); a few anti-biotic wipes; a few cotton balls (in case of an ear ache while riding); a couple of safety pins and a few assorted band-aids. It's a good idea to toss out the contents of your medi-kit, at the start of each rally season, and fill with all new stuff as some of the items you put in it might have expiration dates.
Bungee Cords - If you can't fix it with duct tape you can tie it down with a bungee cord. You can NEVER have too many spare bungee cords.
Favorite Camping Knife - Stuff needs cutting all the time.
Sunscreen & Chapstick - These are another one of those that are kinda self expanitory.
Beads - OK, some might argue that plastic Mardi Gras beads are not a camping essential but then others might argue that they are more important than beer. I'm sure you can find a little extra space someplace to throw a few strands.
