Semper Fi Marine... aircrew here, or, was.
Where are you at right now? I know a few guys at Cherry Point and at Miramar who might be interested.
Personally, I would just flush it out with some diesel, and have someone state-side fire her up every month or two for ya and run it down the street... mom/dad, uncle, little sister? I had insanely bad problems with my '65 Galaxie after coming home from the sandbox... and that was only 7 months sitting in a garage, covered.
Another thought... our current commander-in-chief is rapidly crashing the economy at a precipitous rate. When you come back from Hawaii, assuming there is still a currency called the U.S. Dollar, you might want to consider keeping that system in your truck to offset the pain of paying $8 per gallon for diesel.
