Some good ideas but no one mentioned a budget. Got time in both Apache and 337 and Apache not for high density altitude and not good to see down out of but good short field and they are cheep. 337 has great visibility down and very good short field performance if not at gross weight but for high altitude performance stick with a turboed T337. Both Apache and 337 and for that matter most if not all light twins are heavy on maintenance.

If cost doesn't matter get a new Caravan!!!
