Sometimes you just need to pack the gear, kill the cell signal, and hit the dirt. If your idea of a perfect weekend involves shutting your brain off, carving up an overland trail, and setting up camp miles from the nearest paved road, the 2026 Outside Van Syncline is your rig.

Now available on the ground at Donohoo Auto, the Syncline takes the nimble 144" Mercedes-Benz AWD Sprinter chassis and transforms it into a tactical, gear-hauling basecamp built for two.

The Syncline isn't just a camper; it’s a high-tech off-grid command center.

Outside Van completely overhauled the electrical and navigation systems for 2026. At the heart of the build is a massive 9.6 kWh 48-volt Lithionics dual battery system and a 3200W inverter. That means you can run the 48V aftermarket rooftop air conditioner, the hydronic diesel heater, and the induction cooktop completely off-grid without hesitation.

Managing all of this is the newly integrated Garmin Touchscreen Control Center. It even features a secondary, removable Garmin tablet dedicated entirely to off-road navigation, ensuring you know exactly how to push further into the wild—and how to get back out.

If your adventures require heavy hardware, the Syncline’s layout is engineered around an uncompromising "gear-first" philosophy.

The rear of the van features a massive garage space lined with L-Track mounts, perfect for locking down mountain bikes, overland recovery gear, or climbing equipment. Because serious trail days mean serious dirt, the Syncline comes fully equipped with:

• An on-board air compressor with a 1-gallon tank and three connection points to air your tires back up after crawling over rocks.
• A hidden interior water box containing a shower and toilet.
• A rear exterior shower hookup for blasting the mud off your gear (or yourself) before climbing into the cabin.

Once the gear is stowed, the OSV FoldAway Murphy bed drops down over the garage, instantly converting your utility space into a comfortable sleeping bunker.

The Syncline looks exactly as aggressive as it performs. Rolling on 17" Apex wheels wrapped in all-terrain tires, the van is protected by a No Rub front fender kit and an OSV Combo roof rack. When the sun drops, a 50" light bar, SAE fog lights, and rear roof floodlights ignite the trail, making night operations a breeze.

Custom overland builds of this caliber typically require a brutal 12-to-18-month waitlist. You don't have to wait.

The 2026 Outside Van Syncline is in stock and ready for immediate delivery at Donohoo Auto. Whether you are loading up mountain bikes for a weekend in the woods or plotting a cross-country expedition, this rig is built to take the punishment.
