I have a professionally made drawer set up in the back of my 01 trooper that doubles as a sleeping pad set up. this is made out of 1/2" Baltic Birch plywood and heavy duty drawer slides from Lee Valley, and fits behind the rear seats. Includes an extra piece of plywood that slides forward when the rear seats are folded down to create a 6' 3" sleeping platform. the two pieces lock together with metal dowels. The whole set up can easily be disassembled and set up in your trooper.
