What’s Different/Better About Truma’s Aventa Rooftop RV Air Conditioner?

RV air conditioning is always a hot topic (get it?) because many of us spend time traveling and living in our RVs in hot weather. Since the purpose of an RV is to offer us the comforts of home as we travel, efficient air conditioning is an important matter that commands a great deal of attention. And when any new product enters the market promising a more efficient (and less noisy) air conditioning system, most RVers are interested in learning about it. The Truma Aventa is no exception. This rooftop air conditioner offers some pretty sweet specs and looks mighty promising.

So, in this post, we’re investigating the Truma Aventa and all of its key features.

What Is the Truma Aventa?

The Truma Aventa is a German-engineered air conditioner that combines a remarkable balance of cooling and humidity control to achieve a comfortable RV interior with minimal noise. The Aventa is billed as energy-efficient with a low-profile design.

Originally, Truma’s Aventa units were only available to RV manufacturers, so you’d only be able to get one on select new RVs. The units are now available for aftermarket purchase in the USA, and can be installed by Truma technicians in Elkhart, IN and in Florida (including some certified mobile techs). As we update this article in 2026, however, they’re not currently an aftermarket offering for DIY installation.

But, RV owners wishing to replace their existing rooftop AC with a Truma Aventa may have that opportunity through Truma service technicians. (You’ll need to complete a survey with details about your rig, including photographs and measurements, for Truma personnel to review to determine if your RV is compatible with the Truma Aventa.)

We want to make this clear early on because we dislike spending time learning about an interesting new product only to reach the end of an article to learn that it’s unavailable to us. We’re reporting on the features of this air conditioning unit because we like the design, we think the balance of cooling and humidity control is a winner, and a quiet, low-profile air conditioner is worth mentioning.

So, if you’re looking to upgrade your RV’s air conditioning to a Truma unit, you can obtain installation from Truma factory locations in Indiana and Florida as well as via some mobile service in Florida. Truma offers flat-rate installation for both the Truma Aventa Comfort and Eco, at select Truma factory service locations.

So let’s take a look!

Who Makes the Trumal Aventa?

The Truma Aventa is made by the Truma Corp. in Putzbrunn, Germany.

Truma Corp., named after United States President Harry S. Truman, was founded in 1949 by Philipp Kreis. Mr. Kreis’s first product was a gas lamp which he designed to address an issue he faced with lighting during power outages when he was running a night school teaching English in Munich. Today his company is the leading RV component supplier in Europe.

In 2013, Truma Corp. opened an office in the U.S. in Elkhart, Indiana, an area often referred to as the “RV Capital of the World”, (and, interestingly, it’s also known as the “Band Instrument Capital of the World”). Truma’s Elkhart office handles all of its distribution and tech support in the North American marketplace.

We have considerable personal experience with the Truma brand, as all four of the RVs we’ve rented during international RV trips (Australia, England, Italy and New Zealand) were equipped with the Truma Combi. That’s a combined furnace & water heater that we absolutely loved.

We also had a Truma AquaGo on-demand water heater installed in our (former) Newmar motorhome and we loved it.

How Many Truma Aventa Models Are There?

There are two models of the Truma Aventa – the Eco and the Comfort – both of which operate on 120V AC power (a third model, the Aventa Eco Plus, features a heat pump to keep you comfortable in multiple seasons).

The Aventa Eco offers 13,500 BTUs of cooling capacity (as does the Eco Plus), while the Aventa Comfort offers 15,000 BTUs. Both models can also be ordered with a factory-installed soft-start module (a good choice for anyone looking to run their air conditioner(s) from a large battery bank or a smaller portable generator).

How Long Has Truma Been Selling Aventa Air Conditioners?

Truma has been selling air conditioners in Europe and Australia since the late ’90s, but the North American version of the Truma Aventa was designed more recently, with the comparatively warmer weather of North America in mind, backed by more than 70 years of German engineering.

What Are the Key Features of the Truma Aventa Rooftop Air Conditioners?

Balance of Cooling and Humidity Control

Truma’s Aventa models offer a balance of cooling and humidity control designed to achieve maximum comfort in an RV’s living space. This focus on controlling humidity while cooling the RV is a stroke of genius if the Aventas do it well (which we’ve read they do) because as those of us who have lived in our RVs in areas with high humidity can testify, heat is not always the central issue that needs to be addressed.

If Truma achieves this balance as well as we’ve read they do with the Aventa, they’ve got a winner on their hands.

Three Energy-Efficient, Low-Amp Cooling Modes

Both Truma Aventa models have three manual cooling modes (low, medium, and high) and their three low-amp speeds appear to be very efficient.

• Low speed = 9.4 amps AC (or 104 amps DC)
• Medium speed = 9.6 amps AC (106 amps DC)
• High speed = 10.5 amps AC (116 amps DC)

Ultra-Quiet

The Truma Aventa is marketed as “ultra-quiet”, and we’ve read that in real-world use one can actually hold a conversation without strain near a running Aventa. Truma achieves this by using a thick, noise-absorbing EPP foam core and shock absorber mounts for the compressor, which not only contribute to the quiet operation of these units but also reduce vibration.

Several Operation Modes

All Truma Aventa air conditioners offer multiple operation modes:

1. Cooling Mode: Cooling mode offers the three fan speeds noted above, or the system can be set to an automatic mode which allows the Aventa to select and adjust the fan speeds toward a comfortable temperature. Cool-down happens quickly and efficiently.
2. Air Circulation Mode: Air circulation mode allows you to keep the air circulating in your RV when cooling is unnecessary. Here you can manually choose your preferred fan speeds as well.
3. Dehumidification Mode: Dehumidification mode removes moisture from the air, giving you an effective dehumidifier in your rig. (This could prove to be a game-changer in some climates for sure.)
4. Night Mode: Night mode allows you to operate the unit at low speed with a timer, serving to keep noise at a minimum both inside and outside the RV when you are trying to sleep.

Compatible With Ducted and Non-Ducted Systems

Whether an RV has a ducted or ductless HVAC system, both models of the Truma Aventa are compatible for a seamless installation.

Air Flow Distributor

This feature is applicable to non-ducted installations and allows airflow to be directed downward and to the sides, distributed where it’s most needed.

Digital Thermostat With Remote

Both models of the Truma Aventa come with a remote that has a thermostat control allowing you to digitally set the temperature in the camper for automatic cooling and dehumidification to your desired settings.

They can be controlled wirelessly with the remote control or by using the Truma CP plus control panel (sold and installed separately), and they can be integrated into multiplex systems.

Will My Generator Run a Truma Aventa RV Air Conditioner?

You’d need a 3,000 Watt generator (or a 3,000 Watt inverter) to operate either model of the Truma Aventa. This is due to the power surge required at start-up.

Both models of the Truma Aventa air conditioner can be ordered with a factory-installed soft-start module, helping to reduce the start-up current needed to get the compressor running. We have no information as to whether the Truma Aventa is compatible with the Microair EasyStart Soft Start to handle the initial surge, but that would be a good question for Truma!

When Will the Truma Aventa Air Conditioners Be Available to DIYers?

It’s possible that one day the Truma Aventa models will be available on the aftermarket for us DIY-types. With its reported success in achieving a remarkable balance of cooling + humidity control along with its low amp-draw, low noise, and low profile, we suspect it would be very well received. In the meantime, it’s possible to take advantage of Truma’s flat-rate installation service (which includes the Truma AquaGo Comfort water heater, Truma Aventa Comfort & Eco air conditioners, and Truma VarioHeat Comfort furnace) at select Truma factory service locations (currently Elkhart, IN and Lakeland, FL).
