Here's an equipment list.
You have to become your own expert at packing what is "right" for you. Develop your expertise by making a very complete list of everything you take with you. When you get home cross off the list everything (except emergency items your hope to never use) you didn't use or need.
The single governing principal to packing is, "Less is More." The more you take, the heavier the bike becomes. The stuff you pack becomes a sail. The higher you make the sail, the more wind it catches. The extra weight and sail-effect impact the handling and safety.
I always advise "wear one, wash one." You need only 2 sets of clothes for rinding 3 days or 29 days. If your itinerary takes you to a dress-up event, then take wrinkle-free slacks and a shirt. You might need some light-weight dress shoes.
Camping gear needs to be compact and light. All the stuff needs to be made for back-packing. Save weight by not packing any cooking equipment. The most efficient protocol is to eat dinner before setting up camp and stop for breakfast after packing up. However, it can be more relaxing to go to dinner after settng up camp. The downside is you may be riding in the dark in unfamiliar territory on the way back. Watch for deer to and from the restaurant. (On one trip I saw dozens of deer grazing in a field on the way to the restaurant. I asked my waitress for something quick to prepare and fast service so I could get back to the campsite before dark. That was not a relaxing dinner. Last year I watched 2 deer almost jump out in front of me at about 10 pm. I was going slower than the speed limit and watching carefully. I was lucky.)
Whatever list you make, put these things at the top:
Finally, if your SO is going along and she likes to shop, this must be her mantra: "Do you ship?" The most successful couples put things for the bike in the tour pack and each use one saddlebag for personal items.
