I think the KM would make a good tourer. In my size, large, the head and seat tube angles are 72 and 73 degrees, very road bike like. Compared to the 58 cm LHT the top tube is 1.9" longer, the head tube angle the same, the seat tube angle 0.5 degrees steeper, the 17.25" chainstays 0.85" shorter, the wheelbase 0.4" longer, and the frame and fork weight 0.65 lbs. heavier.
There are no braze ons for racks but Old Man Mountain racks would solve that with no compromises. The OMM disk brake racks would compensate for the shorter chain stays with regard to heel clearance.
You can run disk brakes or cantilevers and the skinniest or fattest tires available.
With fat knobbies it would do much better on the dirt than a LHT. It is designed to accommodate a suspension fork.
With disk brakes you could run 700c, 650b, or 26" wheels.
It is truly a do everything bike.
