Attached is my version of a checklist of gear to pack for a Moto-camping trip. I took liberties with one that Mellow had posted, reviewed other lists, and took notes on my latest trip. I removed items I didn't need or use, and left some that may still need to come off the list. These lists should always be "living documents", subject to constant review and revision.
One way to save lots of packing space is to leave out all the cooking gear & related food. Eating in restaurants can cost a bit more, but it means less gear to pack and more time on the road. Ready to eat snacks can still supplement your diet.
What I've found to be the toughest items to pack are tent poles and other long objects. A tent can be packed into a saddle bag and kept dry or separate from other items, but tent poles tend to be too long. Almost always the poles get strapped across the rear seat. For some that obstructs the view in the mirrors. I'm still working out where to strap on the pole bag to keep my view un-obstructed.
My last ride I took too much in clothes. Riding from snowy conditions to low 70's I was certian I would need a large variety of clothes to keep me comfortable. I was wrong! Future rides I will be more deliberate in packing just enough to keep me from smelling too bad.
