Air Bags w/ Pullrite SuperGlide Hitch

[bw2]

I have a Pullrite Superglide hitch with the under the bed rails that allow for removing the hitch in a F250 4x4. I would like to add air bags. I have looked into the Firestone and the Air Lift companies. I have been told the Firestone air bags cannot be added with the under the bed rails. It appears from reading the materials on the Air Lift site that these will not work as well. I called Air Lift but they were very non-committal and sent me to the technical documents.

Has any one added the air bags with the Pullrite Superglide??

Thanks to all!
