This van has had just one owner from new and was previously fleet maintained. It has been fully serviced and is in excellent mechanical condition. With 128,000 miles, the engine runs exceptionally smoothly and quietly, exactly as a well-maintained Sprinter should. These engines frequently exceed 500k miles when well maintained like his one has been.
Full service history, including documentation for many of the major maintenance items commonly required on the new-shape Sprinter, such as a replacement clutch and an upgraded AdBlue system at 112,000 miles.
12 Month MOT valid until July 2027. It passed with just one minor advisory for a non-essential rear bulb, which has since been replaced. The MOT history is excellent, with no previous MOT failures.
Bodywork
As expected for a vehicle with 128,000 miles, there are a few small exterior cosmetic imperfections. Additional images are available on our website.
We can also offer a range of styling upgrades, including alloy wheels, all-terrain tyres, colour coding and paintwork, allowing you to personalise the van to your own taste.
Conversion
This premium brand new conversion by Graig Barn Campers combines high-end components with practical design to create a comfortable, self-sufficient, off-grid camper for every season.
3-Berth | 2 Travel Seats | Pop up Shower | 230Ah Lithium Power | 300W Solar | Seating for 5
A full-width fixed double bed provides a generous 2 metre (6ft 6in) sleeping length thanks to professionally installed EvoMotion Space Pods, allowing the bed to run widthwise across the van while still leaving a spacious living area. This clever layout delivers living space comparable to many long wheelbase conversions, while retaining the easier driving and parking advantages of the MWB Sprinter.
The premium memory foam mattress, topped with Reflex comfort foam, provides excellent support for a comfortable night’s sleep, while the large garage beneath offers ample storage for outdoor equipment, luggage and camping essentials.
The van has been fully insulated throughout, including the floor, walls, ceiling and doors, using a combination of thermal fleece, closed-cell foam and reflective insulation, selected specifically for each area of the vehicle. To give complete confidence in the quality of the build, a full photographic record of the conversion is available to view, showing every stage before the furniture and panels were fitted.
Heating is provided by a thermostatically controlled 5kW diesel heater, connected directly to the vehicle’s main fuel tank. It can be controlled from the onboard thermostat or via your smartphone, no need to get out of bed to turn the heating on.
Fresh water is supplied by a generous 80-litre internal tank, with a 60-litre underslung waste tank complete with overflow, making the van well suited to extended off-grid adventures.
Off-Grid Electrical System
At the heart of the electrical system is a 230Ah Roamer Smart4 Lithium battery—one of the most advanced and safest lithium leisure batteries available. Combined with 300W of aerodynamic slimline solar, this setup provides an impressive level of energy independence.
The battery can be charged in three ways:
– 300W solar panel via a Victron SmartSolar MPPT controller with Bluetooth monitoring
– 60A Renogy DC-DC charger while driving
– 75A Renogy AC charger when connected to campsite hook-up
When connected to mains electricity, the hook-up powers the internal 240V sockets and induction hob directly. Away from hook-up, these are seamlessly powered by a 3000W Renogy Pure Sine Wave inverter with automatic UPS changeover, allowing you to enjoy full household-style power wherever you travel.
Fast-charge USB, USB-C, 12V and 240V power outlets are positioned throughout the living area, complemented by a combination of LED mood lighting and automatic courtesy lighting.
Ventilation is handled by a remote-controlled MaxxFan Deluxe roof vent, which can either draw cool air into the van during warm weather or extract air while cooking, showering or using the toilet, helping to keep the interior comfortable all year round.
The Kitchen & Washroom
The kitchen has been designed to maximise both workspace and storage while maintaining a clean, modern appearance.
A sleek black glass two-ring induction hob provides fast, efficient cooking and is perfectly suited to the camper’s powerful off-grid electrical system.
The deep composite sink is exceptionally lightweight while still offering plenty of capacity for washing dishes and preparing food.
A 65-litre 12V compressor fridge/freezer keeps food and drinks chilled wherever your adventures take you. The removable freezer compartment can be taken out to create additional fridge space when required, and the fridge can be monitored and adjusted directly from your smartphone.
Storage has been carefully considered throughout. Large soft-close drawers and cupboards are secured using hidden travel locks, keeping everything firmly closed while driving. Once you’ve arrived on site, the locks can be switched off, allowing the drawers and cupboards to open normally without repeatedly engaging and disengaging the catches.
Innovative Pop-Up Shower Room
One of the standout features of this conversion is the clever pop-up shower room.
When not in use, the shower base is covered to create an additional seating area, helping to maximise the available living space. When it’s time to shower, simply attach the supplied curtain to the four ceiling-mounted fixing points to create a spacious, full-height shower enclosure. The lower section is fully waterproof, while the curtain provides unrestricted shoulder and arm room, creating a far more comfortable showering experience than many fixed cubicles.
The portable toilet stores neatly within the shower area and can be used in place or easily moved elsewhere inside the camper for additional flexibility.
This innovative design delivers the convenience of a full shower room without permanently sacrificing valuable living space, helping the camper feel significantly more open and spacious during everyday use.
Living Space
Designed to feel bright, spacious and practical, the living area comfortably accommodates everyday life on the road without compromising on storage or functionality.
Privacy is provided by factory-style tinted side windows, including a sliding driver’s side window that is perfect for increasing airflow while cooking or relaxing. The rear bunk window is also fitted with privacy glass, while blackout curtains and a full cab privacy curtain allow complete privacy for overnight stays.
The fixed two-seat sofa features upholstered Reflex foam cushions for excellent comfort and hides a large storage chest beneath, making full use of the available space.
Opposite is a fixed single seat, which discreetly houses the portable toilet and innovative pop-up shower system without impacting the open feel of the living area.
The front passenger captain’s seat swivels to face the rear, transforming the lounge into a comfortable social space with seating for up to five people. Unlike many camper layouts, the twin front seats also allow easy access between the cab and living area without having to step outside or squeeze through awkward gaps.
A removable, fully adjustable table creates the perfect dining, workspace or coffee table, with a matching worktop finish for a seamless appearance.
For even greater flexibility, the table lowers neatly between the sofa and single seat to create either a spacious L-shaped lounge or an additional 5ft 6in single bed, making the camper a genuine 3-berth.
Storage
Storage has been carefully integrated throughout the conversion, with generous overhead lockers, large soft-close cupboards and drawers, and substantial under-seat storage ensuring there’s a place for everything.
Beneath the fixed rear bed is a huge garage area finished with a durable hard-wearing floor and fitted with heavy-duty tie-down points, making it ideal for securely transporting bikes, outdoor equipment or camping gear.
The garage can be accessed both from inside the camper and through the rear doors, making loading and unloading quick and convenient.
A generous fixed rear double bed provides a comfortable 200cm (6ft 6in) sleeping length, complete with a premium full size memory foam mattress topped with Reflex foam for exceptional comfort and support. Beneath the bed is a huge garage area, offering ample storage for bikes, outdoor equipment and camping essentials.
To achieve this impressive sleeping space, the camper has been fitted with EvoMotion Space Pods. This extends the internal width of the van, allowing the bed to be positioned widthwise across the vehicle while still providing a full 2-metre sleeping length. The result is the spacious living area typically associated with a long wheelbase conversion, while retaining the easier handling, manoeuvrability and parking advantages of a medium wheelbase Sprinter.
For additional sleeping capacity, the removable table lowers neatly between the sofa and single seat to create a comfortable 170cm (5ft 6in) single bed, making the camper a genuine 3-berth without compromising the everyday living space.
