Stone Offroad Design (SOD) has recently taken the overlanding world by storm with the debut of their $1.6-million Peak 6×6 expedition motorhome, designed to seamlessly blend ultra-luxurious living with a rugged, versatile vehicle chassis. As part of SOD’s ambitious Peak Series, the Peak 6×6 epitomizes the merging of rustic chic with a sturdy and reliable off-road design.
SOD, a German builder known for their modern Unimog campers, presents a fresh perspective to the 6×6 expedition motorhome segment, often dominated by established manufacturers such as Action Mobil and Unicat. Their designs stand out, especially on the inside, featuring rugged, photogenic RVs designed for the off-road adventurer who also appreciates comfort and style.
The showcased model, the Peak 6×6 3358-6500, is built on a Mercedes-Benz Arocs heavy-duty 6WD truck chassis, normally used for hauling construction machinery and materials. The vehicle boasts a powerful 578-hp 15.6-L six-cylinder engine coupled with a Mercedes Powershift 3 transmission. In addition, SOD offers the 3352-6500 variant, based on the 520-hp MAN TGX 33.520 6×6.
The transformation from a basic six-wheeled workhorse to an opulent exploration vessel involves securing a 6.5-m (21-ft) motorhome box on a custom hot-dipped galvanized subframe, with a triple-point vibration-dampening attachment system. SOD uses fiberglass-sandwich construction with foam insulation, crafting a shell with a thickness ranging from 60 to 80 mm (2.4 to 3.1 inches), depending on specific build requirements.

Step inside the Peak 6×6, and the true beauty of SOD’s design becomes evident. The layout offers a semi-enclosed rear bedroom centered around a raised double bed. A compact kitchen is conveniently positioned close to the dinette, featuring a cooktop, sink, ample storage, an oven across the entryway, and a standing-height fridge/freezer next to the dining area.
The bathroom layout is unique, located ahead of the bedroom. The design incorporates a toilet at the rear of a long driver-side shower room, while a sink and vanity are positioned across on the passenger side. While this configuration allows for greater separation between the toilet and shower, it may not suit everyone’s preference for a more traditional split dry bathroom.

The interior features a harmonious blend of neutrals and naturals, exuding a sense of warmth and depth. Despite trends predicting grays to fall out of fashion, the Peak 6×6’s gray upholstery and soft-touch wall trim beautifully complement the knotty-grained wood walls, surfaces, and cabinet faces. The structural blacks and appliances add another neutral layer, striking a balance between urban modernity and rustic charm.
Among other notable features, a robust door reminiscent of a bank vault seals off the driver’s cab pass-through. This stylish centerpiece could double as a barricade should the need arise. The coded central door and storage hatch locking system add to the vehicle’s security.

The Peak 6×6 starts at €1.5 million (approx. US$1.64 million), according to a listing on the German vehicle sales site Mobile.de. However, this price can quickly increase depending on individual customization requirements. For those who find the 6.5 x 2.5-m (21 x 8-ft, L x W) motorhome box a bit cramped, SOD also offers the Peak 8×8 featuring a more spacious 7.5 x 2.5-m (25 x 8-ft) box, perfect for those seeking additional room.
In conclusion, the Peak 6×6 is a testament to SOD’s mastery in seamlessly merging the ruggedness of a versatile vehicle chassis with ultra-luxurious living. Its blend of power, ruggedness, and opulence sets it apart from other players in the industry. Whether one is a seasoned overlander or someone dreaming about off-grid exploration, the Peak 6×6 is a one-of-a-kind mobile sanctuary that stands ready to deliver a remarkable and comfortable off-road adventure.
