Replacing entire subfloor one piece at a time.

I once replaced the entire floor in my TT.
Big job to do it right.
The floor sheeting goes all the way to the outside edge front to back.
I literally disconnected everything and jacked the entire walls roof everything up off the floor and replaced rotten joists and plywood in one piece edge to edge.
I used 5/8 T&G
Big job but it can be done.

Then I put new lino down, one piece all the way through front to back.
Then put the walls back down, partitions etc.
