In the world of recreational vehicles, comfort and reliability are crucial, especially when it comes to coping with extreme weather conditions. We are proud to announce that our Oasi 540.1 model recently passed the renowned Truma climate chamber test with flying colours, confirming once again the superiority of Wingamm motorhomes.
Innovation and quality: Wingamm's trademark
The Oasi 540.1 has been subjected to the stringent Truma climate chamber test, an internationally recognised test bed for evaluating the durability and efficiency of recreational vehicles under extreme conditions. This test examines how motorhomes behave under very high and very low temperatures, ensuring that the vehicle can maintain a comfortable and safe interior environment for its occupants.
An unparalleled performance
Our Oasi 540.1 demonstrated excellent insulation and climate management capabilities, thanks to its fibreglass monocoque construction and state-of-the-art heating and ventilation systems.
