Mine is stored in a shed, here in Vt. Last year, I used something called "Shake Away". You spread it around the car, and it keeps rodents away. I also use the mothballs in the shed, and in the engine bay, poison bait around the car too. This year, I'm using used cat litter spread around the outside of the shed. So far, so good. Also, steel wool in the exh pipes is a good idea. Don't want anything chewing on our babies.

Till you get a cover, I would just throw some blankets on it,...better than nothing.
