Just an advisory note about loading your bike equally so that the load is balanced as much as possible.
I loaded my Dominator up with top box, ally panniers etc for a two month stint and found that the front end became really light and dangerous when trying to turn in corners at speed.
I know it sounds obvious, but even sitting as far forward as possible, it caught me by surprise and almost landed me in a ditch just after setting off! - definately not what you want!!
I'm told that most accidents happen shortly after setting off on big trips for various reasons, so just make sure you're familiar with how your bike behaves with a heavy load - take it for a long spin first...
