I think you can have a goose ball without touching the air bags if you don't mind having rails in the bed. My truck has bed rails for a fiver hitch. I bought a goose neck adapter plate that attaches to the rails....made by Reese.

They come with four "L" brackets that bolt to the frame in front and behind the axle. You have to drill holes through the sheet metal in your bed for bolts to connect rails to "L" brackets. Kits also come with spacers to fill in the gaps in the bed so the bed rails rest firmly on the "L" brackets.

This is is just one possibility. Lot of people have airbags so there may be other possibilities.
