Moth balls.
I like to throw a few moth balls in the cab, in the engine compartment and a few on the ground.
keeps the critters away and will air out in about a day.
Stabilizer in a full fuel tank and run the carb dry of fuel, is a really good suggestion.
Change oil and filter in the spring before startup.
Trickle charger on the battery with a cable unhooked.

These are just a few off the top of my head right now.
