Punch line (literally)

It is really quite simple.
If you do this to your Airstream:
(BTW, I am not sure yet how to fix it but I think it will involve a strip of aluminum on the inside of the outer shell and a lot of buck rivets and TremPro 635)

Then this is the result - floor all but gone.
The real good news here is that the frame does not look at all as bad as one would expect based on the floor condition.
I think the punch line dates back to a sick PO who thought that it is necessary to attach a 'skirt' around Naddy to the aluminum when she was no longer allowed to roll on the road. Sad, sad, so sad!

Unfortunately, the PO who stabbed Naddy, did so about 200 times.
So I expect the floor to be as bad all around the trailer. But since we replace it all, who cares?
