Just curious, has anyone made a slide in bed area with storage that can removed and the rear passenger seats be reinstalled? I have a 2013 NV3500 SV standard roof passenger van. I have 16 grand kids, so would like to keep the flexibility to be able to take them (most of them) with us. My wife an I would also like to convert the back to sleeping quarters for long trips when we are by ourselves. Any ideas?
