Gasfrei ausbauen ist beim Camper in der Schweiz oft einfacher, günstiger und schneller. Statt Gasprüfung, fixer Gasinstallation und Folgekosten setzt du mit LiFePO4 Batterie, Solaranlage, Ladebooster, Wechselrichter und Induktionskochfeld auf eine moderne, saubere Lösung für Zulassung und Alltag.

Ein zuverlässiges Wassersystem ist Gold wert – egal ob für Abwasch, Duschen oder Trinkwasser. Doch viele unterschätzen, wie komplex Wasserinstallation im Camper sein kann.

Autark stehen zu können, gehört für viele Camper-Besitzer zu den größten Zielen. Doch welche Solaranlage ist die richtige? 100 W, 200 W, Flexpanel, Mono, MPPT – es ist schnell verwirrend. Hier kommt eine klare Orientierung.

Popular starting points for camper conversions

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.
