Portland maker of modular interior kits for Sprinter and Transit, a middle path between DIY and full custom.
$120k–$180k
View shop7 shops converting vans in Oregon, from Hood River to Tualatin. Every listing shows the chassis they build on, what they will take on and what it costs.
Portland is the west coast's most established custom-build cluster, with several shops that have been converting vans since long before vanlife had a name. Strong on Sprinter 4x4 and on high-end fabrication.
Three shops worth a call, picked for different reasons. Editorial choices, and placement here is not for sale.
Best for Volume and warranty
Portland, OR
Three-year warranty and over a hundred builds a year, so they have met your problem before.
Best for Modular kit builds
Portland, OR
An engineered modular kit rather than a finished build, which is the middle path between a bare van and an eighteen-month wait.
Best for Unlimited custom builds
Portland, OR
Full-custom 4x4 work at the top of the market, for buyers commissioning a vehicle rather than choosing one.

View shopBuilders are listed by state rather than by town because a conversion is a destination purchase, and people cross state lines for the right shop without thinking about it. These are the towns with supply.
We list 7 conversion companies in Oregon, spread across 3 towns and cities. That is the set we have researched and can stand behind rather than every business that has ever converted a van. If you know a Oregon shop that should be here, send it to us.
Published build costs among the Oregon shops listed here run from about $18k to $200k. Those figures are almost always for the conversion alone, so budget another $45k–$70k for the van itself unless the builder sources it for you.
No, and plenty of people do not. A build involves two or three visits over several months, so buyers routinely cross state lines for the right shop. Where local matters is afterwards: warranty work, servicing and the awkward fault two years in are all much easier when the builder is a day's drive away rather than three.
What the quoted price includes and excludes. Whether the queue in front of you is weeks or months. Who does warranty work and for how long. Whether they will service a van they did not build. And what happens to your deposit if you walk away. The answer varies far more than it should.
Worth widening the search, because the shop you want may be two states over, and for a build of this length that matters less than it sounds.
