Description

Voyager 3 is my 2021 Mercedes-Benz Sprinter 144 high-roof 4×4 diesel campervan, located in West Seattle. Asking $89,900 OBO. I’m a very motivated seller. The October 2026 odometer photo shows 55,762 miles.

I had more miles, upgrades and adventures planned with my furry co-pilot. His unexpected passing in 2025 changed the magic. Now I’m looking for a good home where this van’s story and adventures can continue.

The compact 144-inch layout gives you several ways to sleep, eat, relax and work. The rear bed converts to a dinette, both front seats swivel into the living space, and the tables and flip-up surfaces let you change the arrangement throughout the day. Sleeps two, with two belted front seats.

CONDITION

The front bumper has damage from a light bump-and-run in a parking lot at Mount Hood. To my knowledge, it’s purely cosmetic.

Voyager 3 isn’t getting the use and love it deserves in my life anymore. It’s time for a good home and someone who will get back out there. With the Espar D2 diesel heater and insulated window covers, it’s a cozy base for winter adventures.
