This is just a basic list, i`m sure i forgot some gear and a few things depend on the area wich you travelling in.
If you don`t find much villages on your route, be sure you`ve packed enough food/water to survive a few days
Like Michael said, you can test your set up on a campweekend, after that you can ad or drop some gear on your experiences.
Good luck and tell us about your trip,
