Slide floor repair for Everest 343l

[Holens]

Just returned to MI after wintering in AZ and found that the floor of the large slide has pulled away from the rear side wall. I'm still unloading the unit and the damage has me concered about opening the slides. The little I can see looks like the floor is attached with wood screws in tension to the bottom of the wall. Has anyone else had this problem and how did you fix it.
Does anyone have pictures of the walls internal construction?
Thx,
Steve
