I'm wondering does anyone know if the passenger side airbag disables when there isn't anyone in the seat? I'm running out of places to put my kids and I need to put the oldest up front-he's 4. Don't want to have to get rid or my most prized possession!!

Just remember in most states you can have the dealer disable ALL of the airbags if you want. It used to be well known, but has dropped off the radar in recent years.
I think you have to have your insurance company on board still, but at least its' an option.
