Overlander Motorhomes (Doubleback)
At first glance, the Doubleback just looks like a delivery van, but activate the pop-up roof and Doubleback feature and you've got a full-size motorhome hidden in a VW Transporter. The extension in the back adds five extra feet of space, creating room for a bed, kitchen, and plenty of seating. Unfortunately, since the VW T5 isn't available in the U.S., neither is the Doubleback.
The Interior: Once parked, the Doubleback opens up, making space for a bed, kitchen, and extra seats.
