An SUV might look like a great way to escape the grind of city life, but it will be pretty uncomfortable to sleep in. That's why Mercedes-Benz has unveiled the Weekender, a classic style pop-up camper van that sleeps four.

The Weekender is based on Mercedes' mid-sized Metris van, which is about the length of a minivan. In the Weekender, the back seats can fold down to sleep two people, while two more can lie down in a tent-like area that extends out from the roof. The little rooftop bedroom is equipped with a foam mattress and USB ports to power lights and charge electronics. The van also has a separate battery to power lights and devices.

When raised into their seating position, the back seats can move back and forth on rails to create more passenger space or cargo room. Meanwhile, the front seats can rotate 180 degrees to face the back, creating a conversation space when the van is parked.

The tent-like space that rises from the roof of the Weekender can sleep two people.

The Weekender will have an optional pullout kitchen in the rear and a large, roll-out awning to provide a shaded sitting area outside.

Unlike some large RVs, the Weekender will not have a bathroom or shower. Many of those RVs are built from Mercedes Sprinter vans and include plumbing and other features that are added by companies such as Airstream. The Weekender, by contrast, is a simple camper van like the Volkswagen bus campers from the 1960s and '70s.
