2025 Mercedes Sprinter AWD 144 Professional Off-Grid Adventure Build

This is a professionally converted 2025 Mercedes-Benz Sprinter AWD 144 built by Wanderful Wheels in Durango, Colorado. I purchased the van new and had it built for comfortable, self-contained travel while still keeping the maneuverability of the 144” wheelbase.

More than $180,000 was invested in the van, conversion and subsequent upgrades. It has been thoughtfully equipped with premium components from Victron, Van Compass, Owl Vans, Espar, Dometic, Isotherm, Fiamma and others.

This van is compact enough to use comfortably as a daily vehicle, yet has the electrical capacity, heat, air conditioning, water, storage and connectivity for extended off-grid travel. The AWD system, upgraded Van Compass suspension and all-terrain setup also make it exceptionally capable for reaching trailheads, campsites and backcountry destinations.

The build was completed with quality components rather than shortcuts, and I have the original build documentation and receipts for the additional upgrades.

I’m selling because my lifestyle and travel plans have changed—not because of any problem with the van. It’s an exceptionally capable, comfortable adventure van that’s ready for its next owner.
