long term non-use/storage

A little different situation, but you may find some nuggets you can use: When we head for Texas each fall I put Stabil in our Durango and run it for awhile to get the treated fuel throughout the system. Then I connect a battery maintaner to the battery and leave it for 6-7 months. Now, it is garaged, and it's for a shorter term than you're intending, but I believe the packaging on Stabil indicates it's good for a year. Iowa allows me to remove the insurance with no penalty and I remove all but comprehensive coverage. At least then it's covered if a tree falls on the garage. I've been doing this with the same vehicle for the past 9 winters and it's always fired right up when we return in the spring. Hope this helps.
