Although I have a rig totally different from yours, I too will go well prepared with extra fuel, extra water, and plenty of tools and a good repair manual too. I have only had this Goldwing/Hannigan sidecar setup for about 2 months and have not done alot to it. Only big mod was to add a car tire to the rear on the bike. My ride will be about 6,500 miles, leaving in 5 days.
We are pretty heavy, I started figuring out the weights involved, bike, sidecar, trailer. By the time we add our stuff plus us, I figure about 2,300 lbs.....wow. This is our honeymoon trip.
