This 2020 Ford Transit 350 AWD high-roof 148” extended cargo van — known in our family as “Valhalla” — was professionally converted by Mammoth Vans in Kent, Washington and finished with a fully blacked-out Adventure Van Co. modular interior over heather-gray walls and a bamboo ceiling. It’s offered by the original owner with 33,000 miles, a clean title, no accidents, and complete documentation including the original Mammoth Vans build invoice ($27,357), Adventure Van Co. kit receipts, and all service records.
We’re only selling because we’re pivoting to a Porsche Cayenne off-road build and a backpacking-heavy chapter for our family. Valhalla has been our adventure home — meticulously maintained, never abused — and we fully expect to return to van life one day.

Build philosophy — what’s intentionally not included
• No fixed galley plumbing (no sink, fresh/grey tanks, or water pump)
• No internal cooktop (we cooked outside or with portable equipment)
• No solar panels installed (wiring is pre-run for an easy add)
• No interior shower or toilet
This was a deliberate build choice: keep Valhalla a true adventure van rather than a full-time RV. The result is a lighter, simpler, more reliable rig that flexes to the trip — and never sat unused because it was “too built up” for a Costco run or a weekend with the kids.
Known issues — disclosed up front
• Small dent in the driver-side high roof
• Driver-side passenger USB charger is loose
• AMP Research powered running boards have some powder-coat flaking (a common issue on these boards)
• Minor upholstery wear in spots, consistent with use
• Van Compass lift has a “knock” on rapid decompression — a documented characteristic of this lift kit, does not affect driving, ride, or off-road performance
- Carfax will show Vanhalla was stolen. It was quickly recovered (hours). No damage was done to the vehicle. Only a few odds and ends were taken from inside.
Documentation included
• Original Mammoth Vans build invoice
• Adventure Van Co. kit receipts
• Espar heater service records (filter + ECU replacement)
