Roadrat is what I’m thinking of for myself too, winter trainer / tourer that’s not afraid of a towpath or two.
If it is more off road than on then I would be thinking of a Karate Monkey, which is still on the cards 4 me too.
If it’s on the cheap what about a Kona Dew Drop, not steel though. singular Gryphon if it floats your boat, or the Peregrine if you can afford it. For heavy weight the Surly LHT has to be the favourite, or Fargo maybe.
