Rear floor unbolt?

[Burbinite]

Does the rear floor of our suburbans unbolt? It looks to me as if you can remove a few bolts from the rocker panels, from underneath, maybe drill out some spot welds between the front and rear floor panels and the entire rear floor will come out. Is that true? Has anyone done this?

My rear floor rusted from the inside out and is in need of replacement this would make it much easier than cutting and welding (for me).
