The first concept with the full camper comes from a company called Tischer. It's a fairly standard truck bed-mounted drop-in camper box. It features seating for up to three people, a small kitchen with three-burner gas stove, sleeping accomodations, and even bathroom equipment. The bathroom consists of a hideaway sink and toilet and a space for showering.
The other concept has less capability, but a much more stylish execution. It comes from VanEssa Mobilcamping, and it features a 551-pound slide-out kitchen system. It has a cooler, sink and storage for all variety of cookware. It fits completely within the truck bed and slides out past the tailgate for use. It also fits below the classy teak wood bed cover. Fortunately, the kitchen unit doesn't take up the entire bed, either, so there's still space for various camping items.
As cool as these concepts are, don't expect them to come to America anytime soon, since Mercedes-Benz has no plans to bring the X-Class pickup to America. But we can still admire them from afar.
