Around the world - Part 2

A couple of years ago my friend and I did an E/W around the world trip in real time over the span of several months (jobs and family keep the flights short!). We mostly flew in the C208 and Kodiak. Part 2 of this is to potentially fly the globe north/south. We’re looking for a plane that has a higher cruise speed/altitude than the 208/Kodiak, but can still operate out of unimproved airfields. I’m kind of leaning towards the PC-12, but am open to any and all suggestions. Thanks!
