Key Differences at a Glance

Performance vs. Portability

The Dometic FreshJet 2200 is compact and lighter than most rooftop units. This makes it a strong choice for smaller campervans or motorhomes with limited roof space.

Truma Aventa Comfort, while slightly bulkier, offers higher airflow and better distribution, especially in hotter climates. Its size means it may need more planning during installation, but it also delivers robust performance in extreme heat.

Technology Focus

FreshJet 2200 keeps things simple and streamlined. It provides efficient cooling with minimal fuss and integrates with some RV systems.

Truma Aventa Comfort leans into premium territory. It offers extra control options like programmable timers, improved air settings, and optional smartphone control for users who enjoy tech-driven comfort.

A Detailed Comparison of Features and Performance

Cooling and Heating Performance

Cooling Capacity and Speed

With a cooling output of 13,500 BTUs, the Dometic FreshJet 2200 offers rapid and reliable climate control in various weather conditions. It cools small to mid-sized RVs quickly, ideal for travellers who are often on the move.

Truma Aventa Comfort also delivers strong cooling performance and handles warm conditions well. Some users report a slightly slower cool-down under intense sunlight, but performance remains reliable once it stabilises.

Air Distribution and Dehumidification

Dometic uses a straightforward but effective air distribution system. Airflow remains consistent throughout the space without much manual adjustment.

Truma provides more customisation. Adjustable vents allow users to fine-tune airflow, which helps with even cooling and basic humidity control—particularly helpful in muggy weather.

Technical Specifications and Efficiency

Dimensions and Weight

FreshJet 2200 is the more compact of the two. Its size and lower weight make it a preferred fit for lighter vehicles or rooftop layouts that require careful spacing.

The Truma unit is larger and heavier, which may be less ideal for smaller vans. However, for medium to large motorhomes, the added size contributes to better thermal performance.

Start-up Current and Power Consumption

Dometic’s lower start-up current makes it more generator-friendly. It’s also easier to run off limited power sources, which is a big win for off-grid campers.

Truma Aventa Comfort is still energy-efficient but requires a more stable power supply. It may not start as easily on small generators, though it consumes energy efficiently once running.

User Experience and Comfort

Noise Level and Night Mode

The FreshJet 2200 operates at around 45 dB, making it one of the quieter options on the market. That translates to better sleep and fewer disturbances while reading or relaxing.

Truma’s 48 dB rating is still respectable, though it’s slightly louder in operation. Some owners have reported mild vibration during use, depending on installation quality.

Neither model offers a specific “night mode,” but Dometic’s quieter baseline makes it better suited to silent nights on the road.

Controls and Connectivity

Both units come with remote controls. Dometic’s is more basic but gets the job done.

Truma’s remote has more settings, including timers and sleep functions, offering more control over your environment. In some cases, Truma can also be connected to mobile apps for remote operation—an advantage for those who enjoy tech integration.
