Well, mine is an 03 with all the specs that come with that. Stock 06 bench seat with aftermarket backrest. Carried me and my long term camping gear just fine on a 4 day ride. Carries me and my wife just fine as well. FYI, 6'2" 275.
I wouldn't worry about it for the stuff it sounds like you are wanting to do. It will be just fine.
Like some of my adv friends say..."It takes 20 HP to see the world, the rest is just wheel spin"
Keep in mind the amount of work these bikes do in their home country. Loaded for bear. If it gets too bouncy on stock shocks, there are aftermarket improvements for that as well.
Buy it, ride it, don't look back.
