I found a 4x8 sheet of plywood today.
Lots of screws and nails, and some kind of a latch on one side. But, overall not in too bad of shape, other than a little corner damage.
Pretty heavy plywood too. Maybe 3/4"
Also a long 2x4, not in perfect condition, but it will be able to be at least partially reused.
Of course, the "General Trailer" red flag was an earlier road find.
