Convertible sandman?

It is interesting isn't it, sort of a fairly obvious idea, but one that you'd usually dismiss after an hour or so dreaming, (Sandy ute and a van in one go), but it looks to me like its really more of a ute with a lid. (Looks like struts fit across the van section to stiffen it that would sit above the sides of the tray? - not really a clasically useable van section then?) Dunno what ties it down, blew up the pics, couldn't see how that works. But also, when the you cant climb through to the back of course, and the roof over the cabin when the van section is attached... wonder how that works structurally.
