Re: Penthouse Ladder?
Many years ago in a RV store I picked up a nice quality 5' interior ladder that had these tabs at the top. These tabs would slide into a clip plate you would permanently fasten to the bed. This made it easily removable but somewhat stable under use. This was for another application not the penthouse bed so you would need to find a longer one. The same concept could be applied to a home built one too.
