In 2020, Fabian founded waerchzueg.ch to help others with the technical conversion of camper vans. We’ve now grown to a team of 16 people. We live in or travel in campers ourselves and work together to convert a van every year. Victron and over 100 other suppliers regularly train us on how to use their products, and we pass this knowledge on—through conversations, courses, and on our YouTube channel.

Going gas-free is often easier, more affordable, and faster for campers in Switzerland. Instead of gas inspections, fixed gas installations, and ongoing costs, you can rely on a LiFePO4 battery, solar panel system, charge booster, inverter, and induction cooktop—a modern, clean solution for vehicle registration and everyday use.
A reliable water system is worth its weight in gold—whether for washing dishes, showering, or drinking water. But many people underestimate just how complex installing a water system in a camper can be.
For many RV owners, being self-sufficient is one of their top goals. But which solar system is the right one? 100 W, 200 W, Flexpanel, mono, MPPT—it can quickly get confusing. Here’s some clear guidance.
Everyone in the team has converted at least one camper themselves and knows what counts and where the pitfalls are. We take part in at least one test conversion per year, partner training and weekly product training so that we don't get out of practice. No matter what your van conversion involves: We'll help you find and implement the best solution.

Consultations are always free with us. Even if it takes longer. It's best to bring the affected part, your camper and photos with you. You can also take the opportunity to look around the store next to the showroom and talk to other campers on the conversion sites. There is always someone working on one of the 8x4 meter conversion areas. Many jobs are easier to do in the dry. First things first: demand is high. Pitches are expected to be available to rent again from 2027.
You can also ask us quick, simple questions about camper interior fittings via WhatsApp, phone or email - preferably with a photo. You will be put through directly to a technician so that the issue can be clarified quickly and expertly. Our YouTube videos will prepare you so that we can go into more depth during the consultation. They may even solve your problem or serve as a step-by-step guide.

As a rule, camper dismantling proceeds as follows: 1. dismantling and preparation: remove floor and paneling. 2. cleaning and rust: clean, remove paint/rust and treat if necessary. 3. windows and anything that requires a hole to be made through the bodywork. 4. insulation, electronic installations, camper interior and other work.
Before the camper conversion starts, you determine the framework: How many people are traveling with you? Are there children? How do you want to use your camper? To live in, for weekend trips or longer vacations? How much space do you need? How much storage space, self-sufficiency, comfort? Then you choose the right vehicle: How big should it be? How much should it cost? Draw up a rough plan of where the bed, kitchen etc. should be and make the key decisions regarding the fridge, auxiliary heating, shower, battery capacity and solar panels. You can also get free advice on this in our showroom.
