How to prepare a car for storage?

Disconnect battery and periodically trickle charge during winter .... Full tank of fuel ..... Add Seafoam to fuel ... instead of Stabil... seafoam mixes in gas ... stabil sits on top of fuel .... that is all i do and NEVER had an issue for vehicle to sit 4-6 months ... Oh one other thing ... on jackstands by body ... let susp hang.
