I like the top original floor plan but as per reasons suggested, it might not be the best, practically speaking. But it's cool!!! (always something to be said for the "cool factor"!

)
One thing I did want to mention, that I have planned, is, basically, building the bed on a wooden box, as it were, and mounting it on slides so you can move it side to side to make the bed, as well as being able to double your space on one the side for dressing, etc. Of course, it also has to be able to be secured.
I have a foam mattress that will allow me to have drawers on one side with easy access where the bed will mostly stay and then also be able to lift the mattress to open the other side where it will be mostly free span for "long term storage". Or you could use drawers on both sides. Whatever floats your goat.
Just a thought. I'll let ya all know how it works if I ever get my arm straightened out and get to start working on my bus again.
