Keeping food fresh on the road is essential for any adventure. Whether you're exploring Australia's outback, camping by the coast, or living off-grid, the right caravan fridge makes all the difference. From compact coolers to advanced 3-way systems, there’s a fridge for every setup and journey.
We’ve made understanding simple:
Most caravan fridges today are 2-way compressor models. These are designed for solar and battery setups, offering consistent cooling. 3-way fridges are less common now but still useful. They run efficiently on gas and can last 20+ years when cared for. However, they need a level setup and can struggle with 12-volt power.
Another choice is a portable thermo-electric cooler box by Dometic, which can be described as a cold fan-forced Esky. These are best used for short day trips, like picnics or if you drive a truck around delivering items and want to keep your lunch cold. But it’s not recommended as a permanent setup as it draws quite a bit of power when the vehicle is turned off and isn’t as efficient on hot days.
3-way fridges, also called absorption fridges, use ammonia, hydrogen, and water to cool. They run silently and can switch between gas, 12-volt, and 240-volt power. Gas efficiency is a key benefit, with some fridges running up to two weeks on a single 9kg LPG bottle. For free camping, these are great when paired with gas setups.
However, running on 12-volts drains batteries quickly when the vehicle is off. Some models include AES (Automatic Energy Selection) to optimize power use. While gas isn’t free like solar, these fridges are reliable for off-grid adventures.
2-way fridges work like home fridges, using compressor technology. They are ideal for hot temperature environments as they adjust to maintain consistent cooling. These fridges run on 12-volt, 24-volt, or 240-volt power, making them versatile for solar or battery setups.
Compressor fridges are simple to install, as they don’t need venting. They are more efficient than 3-way models on 12-volt power but are slightly noisier. Covers can help reduce sound. These fridges are popular for caravans and van conversions.
3-way fridges need proper venting to release heat and gas outside the RV. They must also be sealed from the cabin for that reason. Compressor fridges are easier to install. Leave space at the back for cables, and secure the fridge to prevent movement.
When travelling, think about what you usually store at home. Hot weather can spoil food quickly, so a good fridge is important. Check out our full range of caravan accessories & fridges today! If you have any questions, call us on: 1300 854 185.
Yes, most caravan fridges, especially 3-way fridges, need to be level to work properly. They rely on the movement of gases and liquids to cool, and uneven surfaces can stop this process. If the fridge isn’t level, it may not cool efficiently or could even stop working. Compressor fridges are more forgiving and can operate on slight angles, but it’s still good to keep them as level as possible.
No, it’s not safe to run your caravan fridge on gas while driving. Gas appliances should only be used when stationary to avoid leaks or accidents. Instead, you can use the 12-volt option while driving, as most fridges can draw power from your car's battery. Make sure to switch back to gas or 240-volt power once you’re parked.
A 3-way fridge can run on gas, 12-volt, or 240-volt power. It’s great for off-grid camping and uses less power when running on gas. However, it needs to be level and is less efficient on 12-volts.
A compressor fridge works like a home fridge and runs on 12-volt, 24-volt, or 240-volt electricity. It’s more efficient for solar and battery setups and works better in hot weather. However, it’s slightly noisier and doesn’t have a gas option. The choice depends on your setup and travel needs.
