I went and looked at the reddit link you posted. Folks had a lot of good info there for you. I was going to suggest the bikesdirect touring bikes but they may not be small enough for you (I'm 5'2", so I keep an eye out for small frames).
Depending on how light you are going your bike would probably do just fine for short tours. I load my LHT with 30-35lbs, and for me that's plenty.
I would consider light to be half that, at most. Then you'd have to invest in lightweight gear if you are camping....
