The key thing I've found is: a single 4x8 sheet of plywood will NOT cover a full-size truck bed.

Inside bed width is more like 60+ inches. The 48 inch bed width is the width of the bedfloor between the wheelwells. The open bed is quite a bit wider than that. This would require using two separate sheets turned sideways so it's not insurmountable, but adds to my concerns about panel rigidity.
You're right, it will not quite fit across a full-size pickup. I think I posted that it would, as well. My bad!

It works perfectly for mid-size and mini trucks, though. For a larger pickup, you could do what you suggested, but you'd want to bond the seam on both sides, or just hinge it at your union point. That would help out, because you wouldn't have to lift it all the way up (weight and leverage) to load a couple small items aft of the axle.
