How do I put together the bunk bed - Winchester caravan

I just bought a Winchester 1970 or 1980. We cant figure out how to put the double bed together. It seems like the little chest of drawers is in the middle of the way.

I saw the post you have about other caravans having a removable chest of drawers that can be placed to complete the bed. But it doesn't seams the case with this one. Any advice?
