$1500 sounds extremely inexpensive to remove the rear fiberglass cap, remove furniture and cabinets, tear up flooring and subfloor. Remove and replace insulation (kill black mold if needed) install new subfloor and flooring, reinstall all the rest of the inside and put the rear cap back in place? I would have guess $5k to $6k.
Still wondering why they have to remove rear cap for a soft floor? Where are the soft spots?
