>>1688814I would recommend a Marin or Kona rigid (no suspension) steel hybrid (relatively fat tires), with a bent for touring (fork mounts for racks).
A Kona Dr Dew or Marin Muirwoods would be great.
Those chromoly frames are somewhat unique amongst hybrids in that they're comfier and better for your purpose.
A (cheaper) aluminium hybrid would be ok but not ideal. Beyond that you might look at drop bar gravel bikes, and touring bikes.
If your budget is sub $500, rather than around $1000+, I would strongly suggest looking used, and look at the rigid 90s mtb thread to see what kind of thing a lot of us ride. If you want recs on a bike like that, post your height and craigslist and I can make some.
