Thanks everyone for your thoughts. It seems that taking the battery out and putting it on the battery tender is the best idea. I suppose it's a gamble with the idle re-learn, but I can't imagine it would seriously do any damage to the car's computer. It's going to the dealer for a service as soon as the spring hits anyway.
Tire dollies are a good idea too I suppose seeing as how the tires are way more expensive than the battery..
As far as moisture goes, I found this after talking with a buddy:
Carbag - Protective jackets for your car or motorcycle
I figure I can slap a car cover on, and then this. The desiccants should keep the car dry and rust free.. I just have to be sure not to eat them... good thing they put that on the bags..
really appreciate the responses and feedback!
