How to prepare a car for storage?
I change the oil, grease it, disconnect the battery. I throw in an open box of mothballs as well to keep rodents out. The smell doesn't bother me and goes away fairly quickly when aired out in the spring. No issues with this method over the last 10 years or so of putting multiple cars away for the winter. I don't use trickle chargers (don't have one or I probably would). I just disconnect the negative side and leave the battery in the car. I hit it with a low amp charge in the spring and haven't had issues with the batteries. I don't jack the car up. I think that is something that you may have had to do back with bias tires but after a block or two mine are smooth and round again in the spring.
