2005 T@B Floor remodel

I recently bought a 2005 T@B Dutchman with floor issue that will need to be replaced, I have gone through the forums to see if I can find any that would assist with location of bolts that would remove the top from bottom and possibly anything else that could assist with doing this project like a video. I haven’t looked all the across the floor yet but I am thinking it will need a whole new floor from what I have seen. Not positive yet. Please help with what you can, thank you
