Sleeping cabins, which can be located above or behind the vehicle cab, provide a comfortable place for the driver to rest. They are designed to reduce aerodynamic resistance. You can save up to 1.5 litres per 100 km and recoup your investment in a few months if you combine it with savings on living expenses. Functional sleeping cabins are designed for vans and commercial vehicles weighing between 3.5 and 26 t. Modern design, material quality, interior equipment with adequate insulation, and the overall number of ventilation holes ensure maximum comfort.
