4x4 2006 E350 fully built! - $32k

Go anywhere in comfort and confidence.

This is a professionally built 4x4 expedition van designed for real travel — from remote Baja beaches to snowy mountain passes. It’s a proven, reliable rig that has taken us across the Lower 48 and Alaska and has been continually maintained and thoughtfully upgraded.

Built by Autarky Expedition Vehicles with a 4x4 conversion by Advanced 4x4, this is a rare turnkey platform that blends durability, off-grid capability, and comfort.

If you’re looking for a van that’s ready to explore tomorrow — this is it.

We are currently living out of the rig, but plans are shifting, and we are looking to travel overseas. It's currently located in Tuscon AZ, but willing to travel within the southwest to meet a serious buyer.

We are currently living in it so please excuse the mess. The rear door seems to have had an issue with the hinge. Some silicone and weather strip seems to have mostly sealed it, but it does look a little askew.
