Z-Line make hinges that that convert a Vanagon rear seat to a bed - but
I'd check the wrecking yards to get a camper rear seat to get the storage
space under, grab the water tank too if you see a basic (early) camper -
then you could rig up a way to rinse down after paddling!  You can check
Bus Boys (who I believe sell them) or search the web for Z-Line

If you find a camper, Also you might want to get the sliding side windows
that have screens for camping. (Other screen alternatives are night use
only ones) Then drill out the rear snaps in the hatch and you can mount a
rear insect screen - avvailable form several suppliers - I got mine from
The Bus Depot and am very pleased with the quality. Search the nooks and
crannies of the van, I found a perfect rear screen this way - but I had
already bought mine!

Finally - get the rear window curtain bars and unscrew the snaps for the
front window curtain and put the word out to the list for a front
curtain.  (or buy a front curtain from me).
