So,  being part of the weekender package, I think that probably makes it
pretty  rare. I think it might be easier to find a later model z-bed and
recover  it.

well i think mark meant "weekender" as in the sofabed option in the seven
passenger hardtop vans.  not so rare.

of course there was the '85-'87 "westy weekender with poptop" sofabed which
 was full width and had the molded plastic sidepanels with the flip out
table and  fixed jumpseat w/ storage box under it. . you could use that
interior as  well.   they came in tan usually but also blue in  '87
