Keep it coming -- great write up!
I've been kicking around the idea of getting a DR - you may be a commerical for one and not know it.
Of course, I've never loaded a DR, but is there some sort of way to hang some of your gear over the back wheel like with saddlebags to get some of the weight lower? I have found on my GS even getting 8 -10 pounds from the top to the sides helps the handling.
Ride more dude!
