Here's my crazy list carried for 15,000km.
a large lunch box full of spares and tools including 2 inner tubes!
1/4 of a tyre (i've acctualy had to cut this up to fix 6 +side wall splits in both tyres
A steel sauce pan - i cut the handle off, but it has a thick bottom and i can cook real food in it.
Water filter (never used)
5l water bag (never used)
Massage ball (never used)
Kindle (never used)
Satnav (stopped using it after 1 month)
2x fuel bottles (1 big and 1 small for cooking)
5ft staff (for fending off the women - very little use
Extra thick ground sheet (i use it every night)
Assorted coins, stones, seeds and other 'stuff' picked up on the road.
Fulñy loaded, i can barely lift my bike, but i can fix almost anything that breaks in the middle of nowhere, eat good food, sleep well, be dry, warm and fend off any beautiful women
