Tourist I think you have underestimated the galley requirements.....
?! more then 2 meters on 2 sides. More then enough volume I would say. Lot's of meals, drinks, ovens, fridge, 2 meter countertop. You can eat at your seat and in the back cabin. I remember the dutch p3c had less galley space and a little table for 4.
I did a generous bathroom in the back enabling crew members to comfortably refresh, and redress themselves during long (refuelled) flights.
are those Twin Mambas hanging off the wings?
Not twin Mamba's
but new gen high power turbo props, think new GE38 / TP400 like rated at ~6000-8000 for this application. PW is also working on something. They are indeed hanging under the wings.
