Sounds like a great trip Dean. You might want to hit the electrical connectors with some dielectric grease. In the past members have had some problems in the rain with their bikes cutting out on them, and dielectric grease is a good preventive fix for that. Also if you haven't thought of it, wrapping everything up that goes in your saddlebags in plastic garbage bags prevents stuff from getting wet in case water leaks inside.

Good luck on your trip. Ride safe and take pics.
