Truma Aventa 10mm roof thickness adapter
The Truma Aventa roof thickness adapter adds one 10mm increment when installing a compatible Aventa roof-mounted air conditioner in a thicker caravan or motorhome roof. It is an installation spacer—not an air-conditioning unit—and each adapter is sold individually.

How many adapters do I need?
Measure the finished roof thickness before ordering. Truma lists one 10mm adapter per additional increment above 50mm, with a maximum roof thickness of 110mm. Order the quantity required for your measured roof and follow the instructions for your exact Aventa model.
The referenced Aventa Comfort installation instructions show that the air conditioner’s supplied adapter arrangement covers roof thicknesses from 25mm to 50mm. Extra 40091-16900 adapters are used where the roof is thicker than 50mm.
Compatibility and installation
This part is not universal across every Truma air conditioner. Truma’s current dealer catalogue groups 40091-16900 with first-generation Aventa accessories. Confirm your air-conditioner model, generation and roof measurement before ordering. If you are unsure, contact us with the model and installation details.
Truma specifies longer M6 mounting screws for roofs over 50mm; screws, the air conditioner, other installation hardware and installation labour are not included. Roof-air-conditioner installation, electrical connection and final safety checks should be completed by a suitably qualified installer in accordance with the Truma instructions.
