I have a bike designed as an all-rounder that tours quite well. My namesake 1979 Peter Mooney. 531 tubing, long chainstays, fender eyes, Lowrider mounts, cantis, 7 speed triple. 700c and 27" wheels work, tires can be huge and still be fendered. It hasn't toured much, but in its early days, I used to ride up a mountain and camp (surreptitiously - I won't say where).

I now ride it loaded every Saturday home from the Farmer's Market. Riding it loaded is no chore at all, and it comes alive when I take the panniers off. (I rode home from work a few years back and did a Bike Palooza tour of Portland's water frountains. I had my panniers full of a week's worth of work clothes, the ride was often at sub-walking speeds and over trolley tracks, etc. Bike handled superbly at those speeds! So much so that I was enjoying it more than those around me.

The Miyata 610 I rode as a fix/commuter/rain/winter bike for 20 years wasn't all that different. Very practical bikes.
