The Owner's Insights on the CoolAir RTX 2000
Idling a prime mover all night to keep your bunk cool is an expensive habit. Fuel, hours on the engine, and a driver who still wakes up hot.
The RTX 2000 is Dometic's answer. It's a 24V parking cooler that sits on the cab roof and runs off your batteries with the engine dead. Dometic rates it at up to six hours of cooling.
2,000W of cooling out of a 32kg unit, and it goes into an existing roof hatch on most cabs. The compressor is a variable-speed inverter, so it winds itself back once the cab is down to temperature instead of hammering the batteries.
Two things to be straight about. It's 24V only, so it's a truck and heavy vehicle unit, not something for your 12V ute. And it cools, it doesn't heat.
You'll also need the right installation kit for your cab. Those are a separate line and they're vehicle specific.
Why You'll Love the CoolAir RTX 2000
- Runs with the engine off. Dometic rates up to six hours of cooling off your batteries, so you stop idling overnight.
- 2,000W of cooling. Enough to pull your sleeper cab down and hold it through a hot night.
- Variable-speed inverter compressor. It winds back once your cab is cool rather than cycling flat out on the batteries.
- Fits an existing roof hatch. Dometic designed it to go into a hatch opening most cabs already have.
- Turbo and eco modes. Pull the temperature down fast, then drop back to save your batteries overnight.
- Digital thermostat and remote. Set it and leave it, and the remote is in the box.

Why You Should Consider a Dometic Truck Parking Cooler
Dometic has been building parking coolers for European truck fleets for years, and the RTX line is the one operators keep coming back to. Vehicle-specific installation kits exist for most common cabs, which is the part that decides whether your fit goes smoothly or badly. Service support in Australia is solid.

How long the RTX 2000 runs off batteries
How long will it really go? Dometic quotes up to six hours. What you get comes down to your battery bank, how hot the night is and which mode you leave it in. Current draw runs from 5 amps at the low end to 30 amps flat out on 24V, which is a wide spread. Turbo pulls the cab down fast and costs you the most. Eco is what you leave it on overnight. Size your batteries around the run you want, not around the headline number.
What installing a truck parking cooler involves
The RTX 2000 drops into a roof hatch opening in your cab, and Dometic designed it around the openings most cabs already have. Where a new opening is needed, Dometic specifies 505 x 500mm with rounded 25mm corners, and the UNI-2 kit carries the cutting template. It suits a roof thickness anywhere from 5mm to 140mm. From there it's an auto electrician or a truck fitter. Get the seal and the 24V wiring right and it's a long-life fit.
Why the RTX 2000 needs a vehicle-specific kit
Truck cab roofs are all different. Curvature, thickness, hatch size and where the wiring runs all change between makes. Dometic solves that with kits built for particular cabs rather than one universal bracket. There are universal kits and there are model-specific ones, and picking the right one is the difference between a clean fit and a fabricated one. Give us your make, your model and your build year and we'll match it before you order.
What the RTX 2000 will not do
It won't heat. This is a cooler, so if you need warmth in the bunk you're still looking at a diesel heater. It won't run on 12V either, so a ute, a camper or a light van is out. And it's not a fridge-style set-and-forget unit that ignores your batteries, because 30 amps at full noise adds up quickly. Match it to a decent bank and it does the job it was built for, which is getting a driver a proper sleep without idling.

Not Sure a Parking Cooler Suits Your Truck?
Start with the voltage. This is a 24V unit, so it's for trucks and heavy vehicles, not a 12V ute or a camper. Next, look at your batteries. Six hours of cooling is Dometic's figure and it assumes a healthy bank behind it, so a tired set of batteries will fall short of that. The honest catch is that it cools and doesn't heat, and it needs a vehicle-specific kit plus a proper install into the cab roof. That's work for an auto electrician or a truck fitter, not a weekend.
