Atacama 4000


Strong and compact world travel motorhome

One of the most popular ACTION MOBIL series is now also available in combination with the Unimog. The Atacama 4000 is the smallest Atacama that ACTION MOBIL has manufactured so far. Constructed on a 231 HP Unimog U4023 chassis, this all-wheel motorhome combines compact maneuverability and power with the well-thought-out comfort of the Atacama cabin shape.

The Unimog and Atacama are made for each other, because the functional and creative Atacama cab is very spacious thanks to the pull-out bed in the rear and the bathroom / toilet section in the front area of ​​the cabin and is therefore also perfectly suitable for smaller 4x4 vehicles such as the Unimog. The Atacama 4000 guarantees functionality and comfort on a relatively small space.

As usual, the new Atacama 4000 keeps the ACTION MOBIL promise in terms of technical functionailty and the interior design: the luxurious fittings and interior of the Atacama 4000 are among the best in the world traveler’s motor home segment. From the small, but well-designed designer kitchen to the cozy living room with an extendable double bed and the modern shower area - nothing to be desired is left unfulfilled. Fridges, freezers, underfloor heating, pumps for the water system, 32 “flat screen televisions and much more are powered by a 4 x 120 watt solar / 300Ah lithium battery system.
