Add stabil and fill up the tank. Might want to hook up a battery tender. Shouldn't have to worry about tire flat spotting or any other issues, that isn't that long. I've heard dryer sheets around electrical keep rats out, but it isn't as good a deterent as moth balls. Problem is moth balls smell so bad you don't want that getting in your vehicle. I store a car about 5 months out of the year and just do stabil and overfill the tires 5 pounds, but those are soft compound. Also use a battery tender. I keep it in a garage, so there may be a few nice but not like you might get. That would really be my main concern. They love chewing wires.
