Has anyone tried this? Updated 6-9-10

I was wandering the pick and pull junk yard today looking for parts and ideas for a new build. I found an electric 3rd seat folding couch-bed out of a full size Van. Well I thought maybe I could take and make a drop floor and be able to sit or lie down. Has anyone tried this. The frame and switches were only 35 bucks so I am not out much if it doesn't work. Any thoughts would be helpful.
