Back in Sept. 2010 I did pretty much exactly what you are describing on my short stepside bed. I removed all the original rotted out bed boards and then used (2) pieces of 3/4" pressure treated plywood. Functionality on a budget and not beauty was the goal. The center seam is covered by a stainless bed strip and the wood is attached to the bed around the perimeter with carriage head bolts.

I have a heavy rubber bed mat that I throw over it now which helps to keep things from sliding around.
