The plywood floor is bolted to the frame via flat head bolts through the "C channel". When you build an Airstream, first there is the frame, then the plywood floor and C channel, and then everything else.

I believe you have to remove the interior skin to expose the C channel at the section of floor you are working on. I also had to remove the belly pan to see the bolts from the bottom. Each outrigger will have one at the outer end. Friends on this Forum told me just to grab the threaded bolt with vice grips and wiggle until the bolt breaks. Their are other bolts through the C channel and just into the plywood to hold the C channel down flat.

Replacing rotted floor segments is a blood, sweat, swear, and tears operation for sure. There are many helpful threads in the Floor Frame section of these Forums.

look at this thread, it helped me repair my floor.
I used a chisel to get the rotten pieces of floor out of the chanels, lots of swearing and complaining.
When you remove the wall panels, it also gives you a good chance to replace the insulation, and re-caulk around the inside of the windows and rivits.

There was no chance of getting some of the bolts out of the c-channel, so I notched the floor around them.

I have already replaced subfloor in bedroom. Did not have to do a shell off or remove interior wall panels. Did not remove bolts that hold floor to c-channel. Just planed and notched plywood and slid in channel. In a tight spot now in closet. Just wondering if a certain tool or procedure to make it easier to remove the strip of plywood left in channel. In bedroom I drilled out holes and used a scratch awl hook to pull out the strip. Had to take many breaks
