Here is a nice Russian youtube video for a Couch / Bed, chair / Bed, and the click clack couch folding bed.

The Chair is at 48 seconds into the video. This could be a nice thing to have in a TD for one person. ( two if made bigger). It has storage for you bed linens. I think it can be made to unfold automatically using cables. It might be a bit heavy. It will add height to your bed if your trailer is high off the ground. It need to be operated all from the side, folding unfolding and changing the linens. The extra height of the bed will require more space under inside cabinets. The arms do not need to be separate, they can be built into the wall and include pop out cup holders, storage reading materials, and maybe laptops

Here it is in my LowBoy Tailgating concept. It is a little tight, Might be better for a bigger TD, as long as it is not too high off the ground.
