After a weekend of Kiwi and German engineering my new van is all set up and good to go. The bed setup turned out quite nice and its easy and quick to change from "sleeping mode" to "five seats mode".
I pulled the back seats out to have more room for all my stuff and put curtains in. But this will probably be an ongoing project so if you have any good ideas how to improve it let me know.
Check out the new photos of the van.
