Syncline – Spec’d For Adventure


Syncline is the culmination of years of research and development. For decades, Outside Van® has been pushing the envelope for what it means to be an Adventure Van. We’ve taken what we have learned building custom vans and condensed that knowledge into an Adventure Van that is mass-produced while still maintaining the quality and serviceability standards that have defined what makes Outside Van® unique.

The 144 All-Wheel-Drive is the ideal chassis for the adventurous-at-heart looking for a unique and capable platform to explore and enjoy the outdoors, and we have developed a new layout that not only packs in the features needed for a premium experience, but also is adaptable for any adventure-based lifestyle.
