Boatycall,
Thank you for your reply. For a second, I thought I got taking advantage by buying this truck brand new. Looks like, I'm not the only one.

Thank you for your comment. I learned something. I had no idea that the overload springs was an option on the super duty on that particular year.
Thank you everybody for sharing your knowledge and experience.
Now it is time for me to shop for some overload springs and install some stable loads. The airbags are doing a great job on this truck with no overload springs but I'd like to control the bouncing feeling… I'm hoping the stable loads will give me a smoother ride.
