I built a simple rear cargo shelf, to have 2 levels of storage, I didn't build it for heavy loads just for light things. I used some good quality Russian 1/2" Baltic Birch 9 ply plywood from my local cabinet wood supplier, surprising only $50 compared with the 3 ply crap at HD and Lowes. I posted it on you tube titled Jeep WK2 rear cargo shelf, a short video, enjoy and build yourself one. 805gregg
