Westfalia in Europe has introduced an interesting new model based on the 6 meter (20 ft) VW Crafter chassis, named after Swedish explorer Sven Hedin:

Features a very functional looking folding rear bed/storage area:

With an intriguing window size slide-out that makes cross-wise sleeping practical for taller users:

Of course we'll likely never see VW Crafter vans this side of the Atlantic but a similar layout on the 20ft Ram Promaster certainly seems viable.
And as a long ago VW Westy owner I always drool at the Teutonic efficiency of modern European campers. Of course I also cursed that old air cooled VW's mechanical foibles, so I'm glad they've updated their base vehicles!
