Why 13.5K narrows the Truma family
Truma's current North American Aventa range separates models by cooling capacity.
The current Aventa eco family is rated at 13,500 BTU/h, while the higher-capacity comfort line is positioned differently.
A camper manufacturer saying “Truma 13.5K A/C” therefore tells us much more than a generic “Truma air conditioner”: it places the installed unit in the current 13.5K Aventa branch.
Why it still does not identify one exact model
Within the 13,500 BTU branch, Truma currently sells several closely related variants:
- Aventa eco;
- Aventa eco + SoftStartRV;
- Aventa eco plus;
- Aventa eco plus + SoftStartRV.
The “plus” versions add heat-pump capability.
The SoftStart versions reduce startup current.
If a camper source gives only “Truma 13.5K”, those features remain unknown.
Shared cooling capacity
The current 13.5K Aventa variants publish 13,500 BTU/h cooling capacity.
This is the family-level characteristic we can safely associate with a camper whose builder explicitly publishes Truma 13.5K.
Cooling capacity is not electrical consumption.
120 V / 60 Hz North American supply
Current North American Aventa 13.5K products operate from 120 V AC / 60 Hz.
That makes them shore/generator/inverter AC loads rather than direct 12 V appliances.
The camper's AC system must be sized for both running and startup behavior.
Running power
Current Aventa eco-family pages publish approximately 1,260 W cooling power under the stated Truma test conditions.
Current consumption is published around:
- 9.4 A low;
- 9.6 A medium;
- 10.5 A high.
These are current-generation reference values.
A production revision/data label remains the final service source.
Startup current differs with SoftStart
This is one of the most important variant differences.
Current standard Aventa eco pages publish a startup current around 59 A RMS for a very short interval.
SoftStartRV variants publish roughly 30 A RMS for the same short duration.
MHS therefore does not tell a Lance 1191 owner that SoftStart is installed merely because the A/C is 13.5K.
Heat-pump capability differs by “plus”
Aventa eco is cooling-only.
Aventa eco plus adds heat-pump heating, with current Truma pages publishing 13,500 BTU/h heating capacity.
This is another feature that cannot be inferred from the 13.5K cooling number alone.
The camper source must say eco plus/heat pump or the data label must confirm it.
Common operating modes in the current family
Truma's current Aventa material describes modes such as:
- manual fan speeds;
- automatic cooling;
- air circulation;
- dehumidification;
- night mode.
These current-family features are useful context.
But exact controller behavior can vary by OEM integration and product revision.
OEM control can differ from aftermarket control
Truma states that aftermarket Aventa can use its included wireless remote.
When installed by an RV manufacturer, it may also be integrated with CP plus or a third-party control system at the OEM's discretion.
That means an OEM Lance installation cannot automatically be described as using only the aftermarket remote.
Standard roof opening
Current Truma Aventa North America material uses a standard 14 × 14 in roof cut-out.
That helps with common RV roof compatibility.
But rooftop and interior clearances around the cut-out also matter; Truma publishes front/rear/side clearance requirements.
Weight and roof load
Current 13.5K Aventa pages publish about 80 lb / 36.3 kg for the rooftop unit/system reference.
This is significant roof mass in a pickup camper.
A roof-lift system, rack and other equipment need to be considered together.
Airflow
The current family publishes multiple airflow levels, with high-mode airflow around 353 CFM / 600 m³/h.
Airflow is not the same as cooling capacity.
A well-distributed lower airflow can still feel comfortable, while poor interior air distribution can create hot zones despite a strong compressor.
Dehumidification
Aventa emphasizes balancing temperature and humidity.
Dehumidification can be valuable in humid climates because comfort is affected by moisture as well as temperature.
It does not mean the camper becomes a controlled dry room independent of ventilation and door opening.
Night mode
Night mode is intended to reduce fan/noise behavior while maintaining comfort.
Published dB values are measured under defined conditions.
The real sound at the bed depends on roof construction, interior distributor and distance from the A/C.
R32 refrigerant
Current Aventa 13.5K products use R32 refrigerant.
This is service information for current products.
Refrigerant service is not an owner maintenance task; the exact data label should be used by qualified service personnel.
Generator and inverter operation
A 1.26 kW running load plus startup demand can be powered by a suitable generator or inverter system.
The word “suitable” matters.
An inverter must support continuous power and startup behavior, and the battery bank must support the DC current.
A small solar array does not make the A/C an indefinitely off-grid appliance.
Solar contribution
Solar can offset some A/C energy during strong sunlight.
But a 300 W solar package cannot continuously supply a roughly 1.26 kW A/C by itself.
Battery/inverter or generator/shore power supplies the difference.
This is a practical example of why power (W) and stored energy (Wh) matter together.
What to check in the camper
Find the Aventa data label and determine:
- eco or eco plus;
- standard or SoftStartRV;
- part number;
- color/air-distributor configuration.
Then confirm how the OEM controls it:
- remote;
- CP plus;
- third-party panel.
That replaces the family relationship with exact product knowledge.
Lance 1191
Lance publishes a selected Truma 13.5K BTU factory air conditioner in the assessed 1191 configuration.
That is enough to link the current 13.5K Aventa family.
It is not enough to claim heat-pump heating or SoftStart, because Lance does not publish those suffixes in the evidence used here.
Why Lance 850/865/975 are not linked from option lists
Other Lance configurators list Truma 13.5K as an optional alternative.
Optional availability does not prove installation.
Those models receive the relationship only if their assessed configuration selects the Truma A/C.
Key takeaway
Truma Aventa 13.5K in North America is a 13,500 BTU rooftop A/C branch whose exact eco/eco-plus and SoftStart variant matters. A family link confirms the 13.5K Aventa architecture while heat pump and startup-reduction features remain unknown until the label is identified.
