Mine is also in hibernation for the winter and has been for a couple of weeks - .
What I did:
Oil and filter change.
STA-BIL in fuel (ran it for a while too, to ensure circulation).
Detailed inside and out with a fresh coat of carnauba.
Box of baking soda inside (helps absorb any odors/moisture).
Tires on styrofoam blocks (prevents flat spots) that are on top of tarps (helps keep cold/moisture from coming up through the concrete).
Covered w/Mopar SRT6 Roadster cover.
Battery is out w/float charger hooked up to it.

Come on Spring - .
