Water damaged RV floor repair part 1

In this video I begin the demolition of all the water damaged floor in my 2005 National RV Dolphin 5355. I purchased this RV in January 2020 knowing that it had a few soft spots in the floor and felt that the repairs would be simple, it turned out to be more work that I expected but it will be worth it in the end. Here is part 1 of 4 videos.
