Hi All, thanks bunches for your responses!
Brad, I believe you're giving me a good understanding without having to take the plunge on a new bike.
Yes, my Trek has lockouts which helps. I think I'll put on some slicker tires and do some light-duty touring and see where it goes from there.
One thing I know is if I go for the touring rig, different bars will be in the works; I never have liked dropouts.
Thanks again!
