Wife and I spent nearly 2 weeks sleeping in the back of our D1 in Tassie last year.
Here's a link to my thread from back then, with some pictures of the sleeping platform I made (page 3). http://www.aulro.com/afvb/discovery-...ping-d1-3.html
Very comfortable (even SWMBO agreed). The only improvement I'd make if I ever did it again would be to have some sort of a tarp or something to put over the back of the car to stop the bedding getting wet while you are getting in and out.
