Do some research on MDO (Medium Density Overlay). I've been told that it is
what overhead highway signs are made of. I replaced the front wall of my
enclosed with it a couple years ago and have had no problems with it. You
may be able to find it 5' wide. Where are you located, I forgot!

Subject: [Shop-talk] 5x8 trailer decking ideas?
Been quiet for a few days, don't want the collective to lose it's edge :-)
I have a 5x8 utility trailer with a mesh floor that needs a more supportive
deck for 2 motorcycles. I'd like to keep it one piece to stop any water
infiltration that might lift the seam.
I've seen 5x8 ply mentioned for ping pong tables, but not in exterior grade.
There is 5x8 diamond plate (slippery and expensive), so I'm looking around
for other ideas before I butt 4x8 CDX together.
