Interesting, I didn't know that Cessna had a STOL conversion kit, nor that people I know locally (second hand) had done a few - they still look under performant compared to the PAC STOL family and have to wonder if they can handle short strips at high altitudes in thin air fully loaded.

PAC STOL's were driven by demands for work horse grunt power at NZ / PNG altitudes. (eg: https://www.youtube.com/watch?v=1_MO5Wfomks )
