We believe that travel should never be about compromise. You shouldn’t have to choose between the comfort of a beautiful home and the freedom to explore the mountains, the coast, or a city. Your home should be able to come along with you.
That's why every Rocksalt is designed from the inside out.
Authentic materials. Generous proportions. No frills. No faux wood. No unnecessary technology.
Just timeless design, smart engineering, and artisanal craftsmanship. We design and build custom-fitted Mercedes Sprinters in Brittany, with each vehicle tailored to its owner’s needs.

A layout designed with the onboard living experience in mind rather than traditional van layouts.
Most camper vans are designed with compromise in mind.
Increase the number of sleeping spaces. Add more amenities. Prioritize technical features at the expense of actual everyday comfort.
Long-distance travel requires something else.
More space. A more fluid flow throughout the interior. More natural light. Better ventilation. Storage that’s actually usable. Less visual clutter. A more peaceful living environment, no matter the season.
The Rocksalt van was designed from the outset around these principles, with the goal of creating a custom Mercedes Sprinter that feels more like a thoughtfully designed living space than just temporary lodging.
Every Rocksalt van is fully customized and designed around the unique way each owner wants to travel and live.

In terms of pricing, our conversions start at €80,000. As a general guide, the demo van featured on our website would cost approximately €90,000, as it is equipped with several additional options. Every van we build is fully customized to meet your needs and expectations.
Open spaces and natural light are at the heart of the Rocksalt philosophy.
The lift-up fold-down bed keeps the entire interior length of the Mercedes Sprinter open and usable during the day, creating a surprisingly spacious feel and allowing for natural movement throughout the van.
The living area, set back two meters, offers a true space for relaxation, without having to constantly rearrange the seating or feel cramped, while the face-to-face dining area, located next to the panoramic window, maintains a constant connection with the scenery outside.
The idea was simple: to create something that many camper vans still don’t really offer—
, an interior that feels airy.
Lighting receives the same level of attention.
Precise, functional lighting supports kitchen activities and everyday tasks, while softer ambient lighting creates a cozy, relaxing atmosphere in the evening.
More than just interior lighting, the lighting plays a key role in how the van feels once night falls.
Long trips quickly reveal the compromises inherent in many conventional layouts.
Poor ventilation on hot nights. Limited kitchen space. Hard-to-reach storage. Dark interiors. Constant battery management. Spaces that become tiring to live in over time.
The Rocksalt van was designed to minimize these constraints as much as possible.
The two-meter king-size bed is positioned near the side windows and the sliding door to promote natural ventilation during southern European summer nights, while offering a direct view of the landscape as soon as you wake up.
The kitchen, designed to feel like a real home kitchen, features a large prep surface, a glass-top gas stove with a refined look, a large stainless-steel sink, and lighting carefully designed to make the kitchen a pleasant place to be, even during long trips on the road.
The storage solutions prioritize drawers and cabinets that are accessible from inside the vehicle rather than a single large rear storage compartment, allowing everyday items to be kept within easy reach without having to constantly get out of the vehicle.
The result is an interior designed to be more fluid, more intuitive, and more serene to live in over the long term.
The Rocksalt interior combines the understated elegance of Scandinavian design with meticulously thought-out functionality.
The real oak and Fenix surfaces were chosen as much for their aesthetic appeal as for their texture, durability, and ability to develop an elegant patina over time.
No visible metal parts disrupt the living space; the finishes are meticulously crafted, and the drawers and cabinets close smoothly with an automatic locking mechanism while the vehicle is in motion.
The goal was not to create a concept vehicle that was off-grid or overly technical, but rather a calmer, more refined environment that would be deeply enjoyable to live in on a daily basis.
The partition between the cab and the living area enhances privacy, insulation, and acoustic comfort, making the rear of the vehicle feel more like a true living space
The Rocksalt van was designed from the outset to remain comfortable both during Alpine winters and during summers in southern Europe.
Multilayer insulation, aluminum vapor barriers, tinted double-pane windows, and thermostatic diesel heating help maintain a stable and comfortable indoor temperature year-round.
Special attention was given to ventilation and airflow to improve nighttime comfort during hot weather while maintaining privacy and discretion.
The van was put through its paces under real-world conditions, ranging from winter temperatures of -16°C in Val d’Isère to summer heat exceeding 40°C in Calella.
The goal was not only to design a van that was technically capable in all seasons, but also a living space that remains airy, quiet, and comfortable regardless of the climate or season.
Autonomy was incorporated into the project from the earliest stages of design.
The solar system, combined with charging via the alternator, provides sufficient electrical independence that external power connections are rarely necessary.
The flexible water capacity of up to 150 liters allows you to travel for extended periods away from campgrounds and service areas without constant constraints.
The systems were designed not to add complexity, but to make the journey more seamless and preserve a sense of spontaneous freedom.
Based on the Mercedes Sprinter platform, the exterior was deliberately designed to be understated and unobtrusive.
The OEM-style integrated windows, tinted glass, and carefully chosen exterior details allow the vehicle to blend in naturally in both urban and rural settings, without immediately giving away its traditional motorhome appearance.
The result is a high-end Sprinter conversion with a refined, subtle character and quiet, capable performance.
Despite its spacious interior and comprehensive features, the van can still be driven with a standard Class B driver's license.
The concept vehicle embodies a vision of long-term comfort shaped by years of real-world travel and in-depth reflection on how to live in a compact space.
Every Rocksalt van is fully custom-built.
Layout, materials, ambiance, storage solutions, and functional priorities are tailored individually for each client, always guided by the same philosophy: a serene design, thoughtful functionality, and authentic, lasting comfort.
