Jackknife sofa bolts

[Guitgary]

Removed the jackknife sofa from our 06 Tioga 31M. The mounting bolts through the floor are installed thread side up. So, the frame of the sofa is placed over the bolts, nuts installed etc. my question is how do I remove those bolts. I’m afraid to push them downward in case they fall into a space below the floor and forever rattle around!!! I suppose I could replace the nut and cut the bolts as flush as possible. Not an ideal fix, though

Any suggestions would be appreciated
Thanks

Look underneath. On my Southwind, the bolts that secure the chairs and recliner go up through a frame member, through the floor, and a nut is installed on top.

On my slide, The bolts go down from the top and screw into a "T" nut. I believe they installed a "T" nut from underneath before they put the bottom cover on the slide. (I can't see anything on the bottom of the slide, just a smooth cover.
