One of the conveniences of having a camper trailer is its ability to be packed down to a smaller size for towing. In some ways, this feature will also influence the size or height of the fridge that can fit in its interior. Thus, the maximum capacity that can be stored by the refrigerator will also be affected.
One of the most common types of trailer fridge is the absorption refrigerator. It is different from the ones found in the home because it does not use a compressor or any moving parts at all to operate. Absorption refrigerators use a heat source (eg: 12V/230V/LPG gas) for energy to drive the cooling system. In addition, the refrigerator relies on the cooling effect of the liquid (ammonia) as it evaporates into a gas.
So, if you want to keep your food fresh while camping, a trailer fridge is needed. This would allow to go on camping for far longer and go to remote places. You can also save more money because relying solely on take-outs and roadside restaurants can get quite expensive especially if you bring your kids with you.

What Are the Types of Camper Trailer Refrigerators?
As mentioned earlier, there are many types of trailer fridges, one of them is absorption refrigerators. The other types of fridges are:
- Eutectic refrigerator: is a compressor driven refrigeration system coupled with a cold storage device such as a eutectic tank which contains a liquid which is chilled and frozen during a refrigeration cycle. Where a conventional refrigeration system requires power all day a eutectic system does not. This results in much lower power consumption and it also lessens the need for stop/start operation of the unit. Eutectic fridges can also be programmed to turn on during the day so it can be charged by solar panels.
- Compressor refrigerator: is powered by a compressor through AC/DC power. This makes it versatile because you can run it off of shore power if your trailer is plugged in or through your trailer’s built-in batteries when electricity is not available. This kind of refrigerator cools faster and more efficiently. They are also unaffected by changes in altitude.
- Absorption refrigerator: can be powered through LP gas. This makes it more flexible compared to other models that require compressors. Absorption fridges are usually 2-way fridges.
Three-way absorption refrigerators with a climate class ‘T’ or tropicalised rating are designed to work in ambient temperatures up to 43 degrees C but often there is a dissatisfaction with their overall performance so we now see the introduction of eutectic refrigerators.
What Should I Look For In A Camper Trailer Refrigerator?

However, are you really getting your money’s worth or is that AUD $3,000 refrigerator too much? These are the things that you should look for:

Does A Camper Have to Be Level for The Fridge to Work?
Yes. For an RV Refrigerator to operate properly it needs to be level. The older the model of Fridge; the more important it is that it is kept level. A good rule of thumb is that the fridge can be plus or minus 2 degrees from plum. That equates to half a bubble out of the level line.

Can I Run My Travel Trailer Refrigerator While Driving?
An RV fridge can be used while driving. Although there are some concerns with running propane while driving, it is still possible. You could also set your RV fridge to use battery power, which is usually enough to last until reaching your destination.
How Long Will RV Refrigerator Run on Battery?
A standard RV fridge, while running on propane draws a negligible amount of current to power the electronic control panel up front- so if that’s the only power draw, your batteries could last weeks. Running it on DC electricity, though, will drain your batteries in about 3 hours.
