The trailer is decked... pic under my personal album. Now to take it off and seal bottom.... Monday the walls get started.
Regarding cutting the floor. I needed to get the deck out of 2, 4x8 sheets of 3/4... saw no need to keep seam in the middle, so cut for max coverage.
Final deck is 63" x104" (queen size, plus dog bed)..
Outside skin will overlap deck so edge won't show.
