Here is my first shot at a floor plan. The sides will overhang the trailer frame. I am trying to decide whether to go the whole 6' or keep it more like 5'6" to maintain the width of my vehicle.
It's just a sketch and isn't to scale. I think, in looking at this, I will probably actually make the bed wider in the next revision. Those boxes along the walls in the middle are meant to be cabinets. Since the drop floor has to fit within the frame, it will only be 4' wide...good in some respects...the porta potty can sit on the "platform" but the the "occupants" legs will have some room to drop to the floor. Likewise with the bed, legs can hang over the edge and in to the dropped floor space. I am thinking the bed will either be a seate (sp?) or perhaps more like a futon, in that the back (were your back rests when sitting) will run trailer width-wise (bed length wise). Those cabinets could then have a pull out/flip up table area.
