Hi guys, well I'm just about ready to start building drawers with the father-in-law. We'll be using 12mm ply, 4 x 1000mm locking freeslide drawers slides, 6 tie down point, roof mounted led light, 2 lighter and usb sockets, marine carpet I'll post photos of materials and progress. We are starting building next Wednesday. Have one question before we start. Do I leave the original carpet down, bare or something else?
