you'll probably find chipboard where plywood should be. probably 5/8 inch thick. its fastened into the "A" frame of the mobile undercarriage with square head metal self tapping screws. from what I've seen underneath one of them, there's like cross purlins that span across the "A" frame welded to the cross members. you may find pressure treated hard to come by in your state - check the building inspector's office first.
