+1 with Bob's suggestions, given that you may also be in the dry part of Aridzona. IF you were in a moist area or anywhere near the ocean, I'd say 'fog' the inside of the tank with a spray can of engine fog or light oil of your choice to keep corrosion at bay.
With the ethanol in the fuel these days, it traps more water in the tank than ever, and Stabil can only help so much. It take a good 15-20 minutes of running, not just idling, to fully dry the exhaust system out after starting an engine, and it also isn't good to let the airhead sit perfectly still and idle for that length of time. You're better off to just make the commitment to let her sleep through the winter until you've got all the parts back together. Put the fuel in another vehicle and use it - this 10% ethanol stuff doesn't seem to do well even sitting for ~1 month, much less 3-4. Stabil has even come up with a new version of the product that is supposed to help with the ethanol blend fuel - just in time for the EPA to approve the gasoline companies to increase the blend to 15%. It might have some environmental benefits, but I think that the drawbacks are presetnly outweighing them..
