I have old pressure treated lumber in mine. The previous owner did it and as the metal strips were missing he just butted it up against each other. Not the answer for a show truck, but for a driver, or in our case it has been used on and off on our evergreen nursery to haul equipment in the field between long "rests" stored awaiting being put back in street legal condition it works well. Looks okay too for a working truck that has been outside for at least the 15 years we have owned it and before that too. Disregard the paint on the bed shaped like parking light surrounds.
