Sustainably produced – for you and the environment
At JULI Vansystem, we've been committed to responsibility from the very beginning. Our conversion systems are manufactured directly in Erdmannhausen – using high-quality, durable materials and a clear focus on sustainability. Short production routes, regional partners, and well-thought-out processes ensure that your camper conversion is not only functional and stable, but also environmentally friendly. This way, you can travel not only freely, but also with a clear conscience.

Panel van vehicle sizes
Not every van is the same – depending on the manufacturer, model, and year of manufacture, there are different heights and lengths, which play a crucial role in DIY conversions. That's precisely why we at JULI Vansystem have developed our modular concept to optimally fit the most popular vehicles, such as the Fiat Ducato, Mercedes Sprinter, or VW Crafter.
