idaho back country flying

[B2C2]

Im considering getting a 337, and was wondering if anyone can comment on its abilities to get in and out of the idaho backcountry. I have read in this and other forums about use of the aircraft in central america and other places that suggest it is capable for short and rough field operations if configured properly. I would not attempt this without proper training, but would like any comments on feasibility and how an aircraft should be best configured for this. ie STOL configurations, VGs, Turbo vs non-turbo etc. Thanks for your help.
