Why would it be a hard slog with a load? The people that have Cannondale aluminum touring bikes claim that those bikes ride much better and smoother with a load than without a load, and that the aluminum has good compliancy with a load. I still tour with an old, steel touring bike from the early eighties that I have had for 27 years, but it is actually a little bit noodly with a 50 pound load on it.
I wouldn't hesitate to try touring with the OP's bike. I would suggest, however, running as wide a tires as his bike will accept and to be sure to run the tires at recommended pressure rather than max pressure.
