We removed the partition and the shelving units and sold them on Craigslist.
Then, we removed the side paneling from the van. So that we could sound deaden and insulate.
To remove the side panelling from the inside of your Sprinter Van, there are panel trim clips that you will need a flat head screw driver and some pliers to remove. Wedge the flat heat under the center round piece and use the leverage of the screw driver to lift that center piece up. Then, take your pliers and pull it out. Sometimes, the outside piece comes too. That is perfect, because we are taking it all out.
