I will attach a few more pics ref floor. If you lift the existing floor there wont be any sound deadening just screws through the ply into the steel floor. I saved all of my ply and used the thicker floor ply to carpet and panel sides and the thinner original side ply panels to cut up and make fillets that I glued onto the steel floor inbetween the raised ribs, then sound deadened. Hope these pics help feed your mental image.Thanks, it has ply lining and floor, but I plan to lift it and see what is underneath. The van has a few 'issues' and I want it to be sound first, before I get too deep.
