RE: Parking for extended period -- how long does battery last?
It is better to not allow the battery to discharge. The plates in a discharged charged battery will sulfate. This is a permanent condition which increases the internal resistance and reduces the amperes available from the battery.
It would instead be bettery to connect the battery to a regulated 13.8 VDC power supply and let it remain at a full state of charge, not over charge.
For the tires, it does not hurt to let a vehicle remain suspended, for extended periods, on jack stands.
Don't forget to clean and dry the vehicle. It does not hurt to have a fresh oil change either.
