Marine Ply ok for Rear Drawers.

thanks for the tips everyone. off to bunnings i go the shorty needs some storage.......once i clear it with the Minister of finances

I used marine ply 12mm on mine. pre-drilled all screw holes and the glued, screwed and covered in automotive carpet.
I used marine ply in case any moisture got into the draws like something spilled while bouncing around off-road.
They are very strong and with the draws all the way out will support themselves.
