My '07 XV-JP is number 3 of the series, and it is not significantly different from the new ones. The biggest change is the tent is now a slightly different design (fewer windows) and a different material. So I suspect that the newer white demo is pretty much up to current spec.

Mine does not, for example, have the "electronics panel" on the driver's side; what's on the panel on the original is spread around different places. And the storage arrangement is consequently different. (Of course, I can't say whether ER might have changed anything on the green one "post-pictures.")
