Fair enough. Sounds like you need one of these on the rear rack tho...:
Carry a gallon or two. They are stack able, can be used with or without the handle rack they sell + there is a locking one if you use the storage case for tools or what have you. Thinking of getting a storage case for my F8GS actually to carry tools & lock it on. Have the option to stack a gas can if needed. Nice.
First Aid & storage:
They are stackable too if you want storage or first aid. Just saw the storage and first aid kits.
