Update…. So frustrated with no o e making e for a Ranger ( plenty for full size trucks available) I decided to make my own…. 3/4” sanded plywood… o e section 20” and one 19” with a piano hinge in the middle. Covered with marine vinyl and held in place by spring latches. Bracing is 1” angle bolted to bed rails w/ five 5/16 stainless bolts and nylocks. Need to clean up a little overspray glue and put some weather stripping down but turned out nice. Easily folded and removed if needed.
