you know, that business of turning the front seats toward
each other, and making a bed across the bottoms could also
be used for an additional bunkbed:

what if you made a contraption to also go across the
'shoulders' of the front seats (turned toward each other
like that), and put the cot/bed/whatever on that?? the seats
should support it, don't you think?
i'm not sure how you'd fasten it to the seats, but that
would give you a bunkbed sort of arrangement: small bunk
below (on the seat cushions) and small bunk above (on the
shoulders). and it shouldn't require any drilling into
pillars or anything.

yeah, i know what you're thinking. :) put it across the
fold-down armrests. nah, i don't think they'd support it
...those things break if you look at them hard!! ;)
