When heading deep into the backcountry, every square inch of your vehicle matters. Built on the highly maneuverable Mercedes-Benz® Sprinter 144” All-Wheel Drive chassis, the Outside Van Syncline was engineered around a simple goal: pack high-end off-grid functionality into a compact footprint without compromising comfort or living space.

Designed specifically to seat and sleep two adults, this off road Sprinter van serves as an agile, purpose-built mobile basecamp. Whether you are navigating tight trailheads, driving remote forest service roads, or setting up shop for remote work, Syncline’s smart layout and targeted utility maximize every inch of the 144 platform.

Syncline’s interior layout strikes a seamless balance between open-concept living and heavy-duty gear management. Moving from front to back, the space transitions intelligently from a comfortable day lounge and kitchen into an adaptable sleep and gear storage zone.

• Driver & Passenger Swivel Cockpit: Both front seats feature custom diamond-stitch reupholstered leather with full swivel capabilities. When turned around, they open directly into the main cabin area to maximize seating.

• Galley & Dining Area: Located along the driver-side wall, the galley kitchen pairs with a flexible dinette setup featuring a removable marine swivel table.

• The Flex-Garage & Sleeping Quarter: Occupying the rear half of the 144 chassis, this zone functions as a high-volume gear garage by day and a full-sized bedroom by night.

1. FoldAway Murphy Bed & Integrated Gear Wall

In a 144″ wheelbase van, fixed bed platforms steal valuable interior floor space. Syncline solves this with an innovative FoldAway Murphy Bed system.

• Gas-Strut Assistance: Assisted by gas-actuated struts, lowering the bed—complete with its custom memory foam mattress—takes only seconds.

• Integrated Gear Wall: Stowing the bed vertically reveals a floor-to-ceiling Gear Wall equipped with L-Track runs and integrated MOLLE storage panels.

• Bicycle-Friendly Engineering: Recessed cutouts under the bed frame provide crucial handlebar clearance. This allows tall mountain bikes or e-bikes to stay safely locked inside while the bed is deployed directly above them.

2. The Water Box Hidden Interior Shower

Traditional fixed RV bathrooms consume significant floor space while only being used a fraction of the time. Syncline features the Water Box interior shower system:

Traditional fixed RV bathrooms consume significant floor space while only being used a fraction of the time. Syncline features the Water Box interior shower system:

• Concealed Bench Design: Stowed inside a sleek bench seat, the shower remains completely hidden until needed.

• Full-Height Deployment: Deploys in minutes to provide a hot/cold interior shower complete with a waterproof privacy curtain and dedicated ceiling ventilation to handle moisture.

• Integrated Cassette Toilet Storage: Houses a dedicated cassette toilet inside the bench structure, maintaining full bathroom functionality without rigid partition walls blocking sightlines.

3. Full Galley Kitchen Setup

Designed for fast, efficient meal prep off the grid, the galley includes:

• Removable Induction Cooktop: Keeps counter space clear when not cooking and offers the flexibility for outdoor meal prep.

• Stainless Steel Refrigerator: Positioned for fast access from both inside and outside the vehicle sliding door.

• Deep Sink & Premium Faucet: Fitted with custom removable sink covers to instantly extend workspace.

• Upper Cabinetry & Electronics Storage: Overhead storage cabinets paired with a built-in microwave and dedicated connectivity cabinet for mobile tech gear.

The functionality of this off road Sprinter van extends well beyond the interior cabin, creating an active workspace outside the vehicle.

• QuickFlip Exterior Table: Mounted flush at the sliding door entry, this heavy-duty, powder-coated steel table flips down with one hand. Paired with adjacent 120V power outlets, it creates an instant outdoor workstation, coffee bar, or bike repair bench.

• On-Board Air System: An integrated ARB Twin Air Compressor features three connection ports and a 1-gallon air tank, making it effortless to air up tires after off-roading or blow off dusty gear.

• Rear Cargo Utility: Opening the rear doors reveals lower-door stuff sacks, MOLLE storage, and a secondary rear exterior shower connection for rinsing off muddy gear, bikes, or dogs before stepping inside.

• Roof Rack & Utility Ladder: A lightweight cargo roof rack features crossbars, L-Track attachment points, and a pre-drilled roof wire pass-through ready for Starlink integration. Access is provided by a side utility ladder, which doubles as a mount for recovery gear like traction boards.

To support extended wilderness stays, Syncline’s technical infrastructure is engineered to run high-draw appliances without relying on shore power hookups:

• High-Capacity Lithium Power: Powered by a lithium-ion battery system paired with a high-efficiency 3200W inverter.

• Dual Charging Capabilities: Charges via rooftop solar power or rapidly while driving via a high-output alternator.

• All-Season Climate Control: Keeps the cabin comfortable year-round using a hydronic diesel heating system (for cabin air and hot water) paired with a flush-mounted rooftop air conditioner.

• Four-Season Water System: Houses a 20-gallon interior freshwater tank and a 22-gallon exterior gray water tank, protected against freezing conditions inside the insulated chassis structure.

By combining an adaptable floor plan with rugged, real-world utility, the Outside Van Syncline delivers maximum functionality in an agile 144″ platform. It proves that you don’t need a massive footprint to enjoy premium off-grid comfort and relentless off-road capability.
