We have Vortex generators which legally increase the gross from 7k to 7368lbs max T/O. Weight and balances are well within limits. Also we run it single pilot most of the time, but have it in our OC to run it two crew when needed. Many government contracts require 2 crew. This is where it gets challenging sometimes. Going from single pilot to two crew, back and forth multiple times a day is a little tricky, all part of the fun though.
Thanks again to all for the words and the advised reading. I'll be checking them out asap.
Cheers
