An Airstream diner instead of a restaurant:

Dining as free as the wind

What is it like to live without the burden of constantly rising fixed costs, rent, staff, and administrative work? The Poumerol family’s story illustrates this. After more than ten years running their own successful restaurant, they made a conscious decision to move away from traditional dining with “Le Montagnard.”  

Now they’re running their mobile burger business with a clear focus on product quality, flexibility, and customer service—free, independent, and just as successful.

Le Montagnard is all about quality—whether it's burgers or cars.

After a decade in the restaurant business, Valérie and Olivier Poumerol decided to take a radical step: they gave up their successful restaurant and developed a mobile burger concept—deliberately stripped-down, but with a consistent focus on quality.

The choice of vehicle fell on an Airstream Diner from our company. As the only licensed Airstream dealer in Europe, we were able to offer the Poumerols not only the iconic design but also professional after-sales services—and the Airstream remains an original factory-direct vehicle, complete with the corresponding warranty, spare parts services, and much more.

Why mobile? The answer: Focus on what matters

Design, quality, and practicality

The Airstream Diner XL, with its striking aluminum shell, turns heads and delivers exactly what the concept promises: quality, craftsmanship, and durability.
Inside, this shell meets a professional interior design featuring well-thought-out layouts, high-quality materials, and reliable technology for daily use.
The difference really shows in everyday use: The Poumerols deliberately chose an original Airstream—with proven construction, a guaranteed supply of replacement parts, and maintenance and service from an experienced partner.
Even after intensive use and even after a winter of snow and hail, the trailer could be repaired without any problems.

Why ROKA?

We combine two key factors:

• professional interior design for daily restaurant operations
• Reliable after-sales services, including maintenance, repairs, and spare parts supply, for many years to come

The difference really becomes apparent during operation, especially with custom-built vehicles. While simple imported solutions quickly reach their limits when it comes to accident damage or durability, a high-quality trailer remains economically viable in the long term.

Conclusion

This example illustrates what really matters in the mobile food service industry in the long run:
It’s not just about having a good concept, but also about having a vehicle that reliably supports that concept.

The Airstream Diner combines iconic design with technology built to withstand the rigors of daily use. Our decades of expertise and consistent service ensure that our vehicles will perform reliably for many years to come.

This is particularly evident with sophisticated food concepts: quality isn’t just about what’s on the plate—it starts with the infrastructure used to prepare the food.
