Frequently asked questions
What van models are your DIY kits compatible with?
We design kits specifically for the Mercedes Sprinter and Ford Transit, the two most popular platforms for van conversions. Each product listing specifies which van models and configurations it fits.
Do I need professional experience to install your kits?
No. Our kits are designed for motivated DIY builders with basic hand tools and a willingness to learn. We always recommend hiring a certified technician for electrical and propane work if you are not experienced.
Can I buy individual components or do I need a full kit?
Both options work. You can purchase a complete galley kit or buy individual pieces like storage cabinets, L-Track mounting rails, or heater kits on their own. Many builders start with big-ticket items and add accessories over time.
How long does a typical DIY van build take?
Most builders working weekends and evenings complete a full conversion in two to six months, depending on complexity. Using pre-built kits cuts significant time compared to fabricating everything from raw materials.
Will a DIY conversion affect my vehicle warranty?
The base vehicle warranty from Mercedes or Ford covers the engine, transmission, and drivetrain regardless of interior modifications. Our kits use non-destructive mounting methods wherever possible.
Can I visit your shop in Boulder for DIY advice?
Yes. We are a build shop first, and our team works on van conversions every day. You are welcome to stop by and see our kits installed in actual vans.
