In the 1960`s I had a caravan with a drop-down double bed very similar to the one in the video except my bed hinged down from within a wall and a hinged magazine rack formed the bed leg at the end. The bedding was kept in place with a couple of ties across the top when not being slept on.
What goes round comes round.
Not sure about the daytime seating . If you sat in the left-hand swivel seat you'd be a bit blocked out. And in the other seats you could only see out on one side.Not to my taste, I'm afraid.
I like the idea of that Transit model though.
