❄️ What It Is

The Dometic RTX 2000 Air Conditioner is a self-contained 12 V rooftop air conditioner and parking cooler designed for vehicles like camper vans, conversion vans, and light trucks. It’s engineered to cool the interior without needing to run the vehicle’s engine, making it ideal for overnight stops and off-grid travel.

🧠 How It Works

Battery-Powered Operation: The unit runs on 12-volt DC power, meaning it can be powered directly from a suitable battery bank (often with solar or auxiliary batteries) without relying on shore power.
Inverter Compressor: It uses a variable-speed inverter compressor, which adjusts its speed according to cooling demand — increasing efficiency and reducing noise compared to traditional fixed-speed compressors.
Roof Mounted: All components are integrated into a single rooftop unit that installs in a standard roof cutout, so there’s no separate indoor and outdoor unit like with traditional split systems.

❄️ Cooling Performance

Cooling Capacity: Around 2000 W (about 6,800 BTU) of cooling power, strong enough for midsize camper vans and similar spaces.
Quiet Operation: The unit runs quietly thanks to the inverter compressor and optimized airflow, which is great for sleeping or relaxing.
Multiple Operating Modes: It typically includes modes like Eco, Turbo, and Automatic to balance performance and energy use.

🔋 Efficiency & Runtime

Eco Mode: In this setting, it draws relatively low current (around ~19 A), helping stretch battery capacity.
Extended Cooling: With a sufficient battery bank, users report runtimes of up to ~12 hours in favorable conditions — making it useful for overnight cooling without shore power.

📊 Key Benefits

✔ Portable & independent: No need to idle the engine or plug into shore power to cool the cabin.
✔ Efficient and quiet: Inverter technology reduces power draw and noise.
✔ Easy control: Digital thermostat and adjustable fan modes let you fine-tune comfort.

⚠️ Installation & Use Notes

Professional installation is recommended for safe electrical integration and sealing the roof.
Many installations require additional wiring and install kits not included with the unit itself.
It’s mostly marketed for vans and trucks, and use in larger RVs may require checking compatibility with Dometic’s support.

In summary, the Dometic RTX 2000 is a powerful, efficient, and flexible DC rooftop air conditioner designed to keep your vehicle interior cool without shore power — ideal for vanlife, overnight truck parking, or off-grid adventures.

For installing the Dometic RTX 2000 Air Conditioner on a vehicle roof, you’ll need to cut a specific opening in the roof/ceiling to allow air intake and return airflow—this isn’t just the outline of the unit itself but part of the return air system.

📏 Cut-out / Roof Opening Size

The recommended roof opening size you must cut is approximately ****18.9 inches × 15.3 inches (480 mm × 390 mm)**.
- This is not the entire footprint of the air conditioner but the required cut-out for the intake/return area.

📐 Additional Dimensions (for context)

While not the cut-out itself, the unit’s physical size helps plan the surrounding space:

External footprint (overall unit size): ~25.4″ (length) × 33.9″ (width) × 6.6″ (height)
Internal dimension (inside roof opening area): ~15″ (length) × ~14″ (width) × ~5″ (height)

📌 Installation Notes

The cut-out functions as part of the air return system — it’s not just a hole for the cabinet to drop through.
The unit is designed to fit between roof reinforcements or over existing roof vent openings where possible.
Proper spacing from roof structure and support beams is important when making the cut.

Air Distribution Box and Power Cable are included
