My opinion of bikes I have/had and have toured on (and they are just my opinion):

Really Like, fully loaded:

Lotus Odyssey (favorite)
Trek 790 Hybrid (converted to drop bars)
Miyata 1000 LT
1985 Schwinn Sierra (MTB)
1987 RD Coyote (MTB)
1984 Trek 830 (MTB)
Lotus Éclair (1983)

Kinda like, probably better for credit card/shorter tours

Centurion Pro Tour
Trek 520 (1984 and 1989 versions)
Schwinn Passage
Trek 614 (1982 model)
Novara Randondee (1998)
