When I lived in Ohio I kept one of my cars in a pole barn that had a concrete floor. When I stored it in the winter I put the car in a Carjacket.
http://www.carbag.com/It's a zippered plastic bag (think plastic tarp type material) you put the vehicle in. They also sell large perforated steel cans of desiccant as well as bags of desiccant.
What I did was unzip the bag, drive the vehicle onto it, remove the battery, prop the hood and trunk partially open, roll the windows half way down, place a desiccant canister inside the vehicle, place another under the vehicle, put the car cover on the car, then lift the rest of the bag over the vehicle and zip it up.
The desiccant containers can be re-used after baking them in an oven.
Worked great. I now live in Colorado, dry enough that I no longer "bag" the vehicles.
Hope that helps
John
