No actual 920 owners here AFAIK. Not a big seller so far.

Surly Disc Trucker is probably better/safer choice. Tough steel frame. No oddball low-spoke-count thru-axle wheels that are more likely to fail and leave you stranded with low probability of quick replacement. Triple crank drivetrain has wider gear range, smaller steps between gears. SDT is available in smaller frame sizes with 26" wheels, which fit wider range of riders, are perhaps longer-lived wheels, and 26" tires are more readily available than 700c in Third World locations. SDT costs less and been made for 4 years now, probably in the thousands by now, all the bugs worked out in manufacturing/assembly.

A 140 lb rider is probably fine on 28h wheels, but the weight savings of 16 spokes and nipples is insignificant in most loaded tourists' views, while the additional 29% spokes sounds like a real good idea given that wheels are one of the biggest problem areas on touring bikes. If you plan on leaving the pavement, then steel frame and more spokes is a good idea.
