ROFLMAO.... I read this to say "store in a place with no sunlight and put on a solar battery charger"

Greg..
You can simply drive them in and park them. I'd disconnect the batteries and possibly remove them (to a piece of wood on the floor) in case they leak you won't corrode the vehicles.

When you get back..charge the batteries and start the cars... It isn't like you are storing for years. I've never seen stabilizer hurt or help.. Honestly..that is all I would do.

Having put many boats and bikes up for storage, I offer the following suggestions. A fuel stabilizer like Sta-Bil is highly recommended. Make sure you run the engine long enough to get the stabilizer into all of the fuel system. Marine stores sell an engine fogger that is designed to protect the innards of the engine and is easy to use. Of course, change the oil and filter. As mentioned, putting the car up on jackstands is best but if that is not possible, air up the tires and try to park it on something other than dirt. Tire covers would be a good investment also. Either cover the car or make some shades out of cardboard to cover the insides of the windows to avoid sun rot. A fine spray of silicone on the engine will keep things from corroding. Disconnect and remove the battery, keep it stored inside and keep it charged up. I have seen rigs stored in this manner for up to 18 months and fire right up. Of course the best thing for it is to have someone fire it up and drive it around once month, but that is not always possible.

Sidenote: I for one appreciate you and your families sacrifice by serving in our military. Stay safe and keep your head down. We want to see you back on OUR roads soon.
