Ready to transform your road trips into mountain biking missions? Outside Van’s Syncline model is a high-performance adventure rig designed specifically for those who live to ride. Built on the Mercedes-Benz Sprinter 144 chassis, this van balances off-grid capability with all the technical features needed to support an active outdoor lifestyle.

In our latest feature video, we joined up with pro riders at Jarrod’s Place Bike Park in Summerville, GA, to put Syncline to the test. From hauling gear to providing the ultimate basecamp, this build is all about technical mastery behind the walls.

Syncline isn’t just about good looks; it’s about the infrastructure that makes off-grid living seamless. As a Fox Factory division, we’ve integrated top-tier suspension technology to ensure your journey is as smooth as the trails you’re chasing.

1. The Foundation: Mercedes-Benz Sprinter 144 AWD Chassis

The ultimate adventure requires an agile, highly maneuverable foundation. The Syncline utilizes the premium Mercedes-Benz Sprinter 144 wheelbase with an All-Wheel Drive (AWD) drivetrain.

• Trailhead Agility: The compact 144 wheelbase allows you to confidently navigate tight switchbacks, rugged forest service roads, and standard city parking spaces.

• All-Weather Traction: The advanced AWD system provides optimal power distribution, ensuring you can reach remote trailheads and winter basecamps without hesitation.

2. Premium Off-Road Performance & Suspension

We don’t just build vans; we optimize ride dynamics. Leveraging our integration with Fox Factory, the Syncline delivers unmatched stability and off-road capability.

• FOX Suspension Upgrades: Outfitted with custom-tuned FOX suspension kits, significantly reducing body roll and improving handling when fully loaded with heavy gear.

• Off-Road Wheel & Tire Package: Equipped with rugged all-terrain tires and premium off-road wheels, offering maximum traction on loose dirt, mud, and gravel.

• Premium RIGID Industries Lighting: High-output LED lightbars and integrated trail lights ensure maximum visibility during late-night arrivals at camp.

3. Smart, Space-Saving Interior Engineering

Maximizing a 144 wheelbase requires intelligent, multi-functional design. The Syncline features a layout that prioritizes open living space without sacrificing utility.

• The “Water Box” Hidden Shower System: A patent-pending, space-saving design that tucks away when not in use. It gives you the full utility of an indoor shower without permanently eating up valuable floor space.

• FoldAway Murphy Bed & Gear Wall: Sleep comfortably at night and haul heavy gear by day. The bed seamlessly folds up against the wall, revealing an integrated L-Track system and MOLLE panels for secure, customized gear storage.

4. Heavy-Duty Trailhead & Toy-Hauler Utility

Built specifically with mountain bikers, overlanders, and outdoor athletes in mind, the Syncline serves as an active mobile garage and workstation.

• On-Board ARB Twin Air Compressor: Mounted internally with easy exterior access, allowing you to seat tubeless mountain bike tires or quickly air back up after a grueling off-road trail run.

• Premium Gear Storage Integration: Custom gear garage layouts featuring optimized storage solutions to keep helmets, tools, and armor organized.

• QuickFlip Exterior Table: A drop-down exterior workspace perfect for trailside bike tuning, staging gear, or prepping a quick post-ride meal.

5. Uncompromising Off-Grid Power & Climate Autonomy

True exploration means leaving the grid behind without leaving comfort behind. The Syncline is engineered for prolonged off-grid power independence.

• Massive Lithium Backbone: Powered by a high-capacity Lithionics battery system (for 2026 models), providing massive amp-hour capacity without the need for a generator.

• High-Efficiency = Climate Control: Utilizes advanced flush-mounted Nomadic A/C units, keeping the interior ice-cold while preserving valuable ceiling height for interior mobility.

• Dual Alternator Charging: A secondary alternator charges your lithium house batteries rapidly while you drive, ensuring you arrive at your next destination fully charged.

Whether you’re shuttling riders to the top of the mountain or enjoying a post-ride drink from the integrated refrigerator, the Syncline acts as the heart of your adventure. In the video, you’ll see how the compact 144 wheelbase allows for incredible maneuverability on rugged forest roads while still offering a fully functional kitchen and sleeping area.

If you’re looking for a van that matches your passion for technical trails and off-grid exploration, the Syncline is built for you.
