Of course, you will get lots of opinions when you ask a question like this, but here goes anyway.
I take my Mustang off the road in the winter. I get an oil and filter change, clean it thoroughly, and fill the tank to the max. I make sure it is fully hot before parking it. Hot includes the trans and the axle, as you do not want any condensation there.
I do use a battery tender.
If it is going to sit for more than two months, I wait for a nice dry day, and start the car. I then drive it till it is fully hot, and make sure to cycle the air conditioning system on.
My rationale for this is that I want to circulate the oil in the engine, trans, and axle, and I want the seals in the AC system to be wet and flexed a bit. It also means that the brakes are used, and the fluid moved around in the cylinder and the calipers. This also eliminates the problem of tire flat spotting, although I've not found this to be a problem with other cars that I've left for longer periods of time.
I do realize that you are not in a position to do all of the above, but there's my answer anyway.
