How Fabian Viaja Stayed Cool in Texas Heat with the TURBRO Greenland 12V DC RV Air Conditioner
Summer road trips through the southern United States can quickly become uncomfortable without reliable air conditioning. For overland travelers and camper owners, sleeping in a vehicle after a day of driving in triple-digit temperatures is often one of the biggest challenges.
During his journey through Texas, Fabian Viaja, a well-known Argentine travel creator who documents his overland adventures across the Americas, found himself facing exactly that problem. While preparing to attend Copa América matches in Dallas, Fabian documented the installation and first impressions of the TURBRO Greenland 9,000 BTU 12V DC Inverter Rooftop RV Air Conditioner on his custom-built camper.
This customer spotlight is based on Fabian's real-world experience. You can follow his adventures on Instagram at @fabianviaja and on YouTube, where he shares RV travel, DIY camper projects, and life on the road.

Camping in 100°F (38°C+) Texas Weather
Texas summers are no joke.
While traveling through the Dallas area, Fabian explained that daytime temperatures regularly reached 38-40°C (100°F+), making it increasingly difficult to stay comfortable inside his compact camper. Before installing the rooftop air conditioner, he even borrowed a portable AC unit to cool the sleeping area at night so he could get some rest.
After arriving at a friend's property outside Dallas, Fabian revealed that a new TURBRO rooftop air conditioner had arrived, calling it an upgrade that would "change my life" during the remainder of his summer travels.
Installing the Greenland 12V Air Conditioner
Fabian installed the Greenland on the roof of his custom overland camper.
Like many DIY camper conversions, his build presented a unique challenge. The camper's roof wasn't perfectly flat, so he needed to fabricate a spacer to compensate for the roof's curve before permanently mounting the unit. Rather than seeing it as a major obstacle, Fabian explained that it simply required a bit of creativity and problem-solving.
Before finishing the wiring, he temporarily connected the Greenland directly to his battery bank to verify that everything operated correctly before making the permanent electrical connections.
For anyone considering a rooftop AC installation, Fabian's project demonstrates that the Greenland can be adapted to custom camper builds with some thoughtful planning.
Running Directly from a 12V Battery
One feature that immediately impressed Fabian was the Greenland's native 12V DC operation.
Unlike many traditional rooftop RV air conditioners that require shore power, a generator, or a large inverter, Fabian pointed out that the Greenland connects directly to a 12V battery system.
During his walkthrough, he highlighted several key features:
- Native 12V DC operation
- 9,000 BTU cooling capacity
- All-in-one rooftop design with the complete refrigeration system contained inside the unit
- Direct battery connection without requiring additional AC conversion equipment
For off-grid travelers, this simpler electrical setup can make installation easier while eliminating the inefficiencies associated with converting battery power from DC to AC.
Real-World Cooling Performance
With the installation temporarily wired for testing, Fabian powered on the Greenland while the interior of his camper measured approximately 30-31°C (86-88°F).
After only a few minutes of operation, the cabin temperature had already dropped to 28°C (82°F), despite the system still being connected with temporary wiring.
Standing directly beneath the air outlet, Fabian immediately noticed how cold the airflow felt and described the cooling performance as "spectacular."
While every RV or camper varies in size and insulation, Fabian's experience offers a practical example of how quickly a properly sized 9,000 BTU inverter air conditioner can begin cooling a compact living space during hot summer weather.
Why a 12V Rooftop Air Conditioner Makes Sense for Off-Grid Travel
For many RV owners, traditional rooftop air conditioners come with tradeoffs. They often require shore power, a generator, or a large inverter capable of handling compressor startup loads.
The TURBRO Greenland takes a different approach by operating natively on 12V DC power. For solar-powered campers, van conversions, and overland vehicles, that means fewer components, a simpler electrical system, and efficient operation directly from a compatible battery bank.
For travelers like Fabian who spend long periods camping away from hookups, those advantages can make day-to-day life on the road significantly more comfortable.
Final Thoughts
Watching a product perform in real-world conditions often tells a more complete story than specifications alone.
Fabian's installation highlights several advantages of the TURBRO Greenland 12V DC Inverter Rooftop RV Air Conditioner:
- Native 12V DC operation
- Direct battery connection
- Fast cooling in Texas summer temperatures
- DIY-friendly installation for custom campers
- Compact all-in-one rooftop design
- Ideal for overland, van life, and off-grid RV travel
Whether you're building a camper from scratch or upgrading your current RV, Fabian's experience demonstrates how a 12V rooftop air conditioner can make summer travel far more enjoyable without relying on shore power or a generator.
