Double-duty functionality is the hallmark of any camper van build.  The more ways you can employ any one part of your van, the more space you save and the less you need to bring with you.  Seat swivels from Nomadic Supply Company allow you to sit in your front seats as normal while driving, but once you reach your destination you can then spin your seats around.  This opens up space in the back and allows accessible comfortable seating without the need for additional chairs or relocating outside the van.
