You mention wanting upright riding, so a super wide drop bar on the lht wouldnt help.
Novara Safari perhaps? There are some in various stores, even though it isnt available online.
REI will come out with new adventure models in early spring. Pretty sure something like the Safari will again be in the linehup.

Looks like your perfect bike is...
- traditional touring frame design
- trekking bar for upright riding and multiple hand positions
- disc brakes
- not truck like ride
