Do not take a station pilot job on the advice of a message board. (It's doubtful you will get enough flight time as a station pilot to make a dent on the mins required if your V22 time does not count. If that is the case, spend your last tour back in Texas as a T34 IP. Texas, because MATSG cannot stick you back in the TH57 as a rotor instructor.)
Leatherneck, you are not the first Marine to walk this road. Ask around, quietly if need be, but your brothers have walked this road before. I am betting V22 time would be considered fixed-wing time (regardless of how the FAA has it classified). Why not just man up, call the airline’s HR department, and ask them directly. The SWA people dept. will return your call or email with an answer. My .02 cents for what it is worth.
Semper fi,
