Sprinter 144 DIY Interior Conversion
This guide is for installing the entire Adventure Wagon Interior kit in a 2007-present 144 Sprinter Van. There are a few differences with electrical installation between the NCV3 (2007-2018) and VS30 (2019+) sprinters for electrical wiring and it will be noted below. Also the guide is targeted for Crew and Cargo version vans. If you have a Passenger van there will be some customization required in the ceiling for Air Conditioning units as well as leaving the rear wall panels off where windows are present. Please call one of our installers or our tech support team for more information on passenger installs.
Any additional written build notes below will be the most up-to-date instructions and the video should be used as a baseline.
Installation can be done over four to six days but can vary significantly based on skill and experience. It helps to have two people for A-frame bracing, track and panel installation.

The heart of our Interior system is our A-Frame wall bracers and ceiling struts. We have modified how the wall bracers get installed please see our additional notes:
- If your ceiling braces (ribs) are not aligned with our centering tool then refer to the video guide below for how to measure yourself and center your ceiling speed struts:
- We are no longer using the magnets to align the wall bracers, instead we use set screws included with your kit.
- If you've used self tapping set set screws to temporarily hold the wall track in place, please remove once the track is fastened to ensure the L track lays flat against the wall bracer
- Be careful when drilling vertical wall bracer holes that you do not accidentally clip the wiring harness. To avoid this you can temporarily pull out the electrical harness.
- Do not install your upper wall Thinsulate insulation until after your wiring chase is installed to avoid leaving shavings in the insulation
