A 20-pound tank of propane will last most trailers a month

The efficiency of your RV fridge is influenced by several factors. Firstly, it's important to ensure that your RV is level when parked, as absorption refrigerators perform optimally when they are sitting on level ground. This is because the gravity feed of the cooling system's fluids plays a crucial role in their operation. Operating on uneven ground can lead to reduced efficiency and even mechanical issues over time.

Additionally, the surrounding temperature and the internal temperature of the fridge when you start it up can impact how long it takes to reach optimal refrigeration temperatures. It's recommended to pre-cool your food before placing it in the fridge or adding cold items first to reduce the thermal load on the system.

Another factor to consider is the ventilation around your fridge. Proper ventilation is crucial for safety reasons, as it prevents carbon monoxide buildup, which is a byproduct of propane combustion. It also helps maintain the efficiency of your fridge by ensuring that hot air doesn't accumulate around it, which would otherwise increase the cooling load.

It's worth noting that while a 20-pound tank of propane can last for about a month, you also need batteries to ensure that everything runs smoothly. The control board, igniter, and thermostat of modern RV fridges require a small amount of electricity to function properly. Therefore, it's important to have a well-charged battery to power these components.

In conclusion, a 20-pound tank of propane will last most trailers about a month, but this duration can be influenced by various factors, including the size of your RV and fridge, the surrounding temperature, and the efficiency of your setup. By ensuring proper levelling, ventilation, and pre-cooling of items, you can optimise the performance and longevity of your propane supply.

Propane fridges are very efficient

Propane fridges are also reliable due to their lack of moving parts, which means there are no parts to wear out, making them incredibly dependable and long-lasting. They also require minimal maintenance, as they only need to be cleaned twice a year by cleaning the burner area and flue tube.

Additionally, propane fridges are quieter than electric refrigerators, and they can run colder than electric units. They also have fewer parts, reducing the chance of failure. Propane fridges are a great option for those seeking a reliable, efficient, and cost-effective cooling solution.

The efficiency of a propane fridge also depends on its size and the size of the propane tank. For example, a 20-pound propane tank can run a 60–368-litre fridge for 9 to 34 days. A standard 8-cubic-foot propane fridge can run for about 10 days on a 20-pound propane tank.

Furthermore, propane is readily available and can be easily transported, making it a convenient fuel source for those on the move. Propane-powered appliances, including refrigerators, have also become more efficient over time, with better fuel economy and lower emissions.

Overall, propane fridges offer a great return on investment, providing reliable and efficient cooling while being cost-effective and low-maintenance.

A battery is required to run the control board

A camper fridge can run on propane for a long time, depending on the size of the propane tank and the fridge. A 20-pound propane tank can last 9 to 34 days, while a larger 420-pound tank can keep a camper fridge running for months.

To answer your question about the control board, yes, a battery is required to run it. The control board regulates the temperature of the fridge and freezer compartments, and it needs a power source to function. The battery powers the control board, allowing it to maintain the desired temperature inside the fridge. This is essential for keeping your food and drinks cool while camping or travelling in your RV.

The battery requirements for the control board can vary depending on the make and model of your camper fridge. Some control boards may be designed to run on 12-volt or 24-volt DC power, which is typically provided by a leisure battery in the RV. This type of battery is designed to power appliances and devices that require a consistent energy supply. It's important to ensure that your battery is in good condition and has sufficient charge to power the control board for the duration of your trip.

Additionally, some camper fridges may have more advanced control boards that can be connected to a smartphone app for monitoring and control. These smart control boards may have additional features, such as Bluetooth connectivity and temperature adjustments. In such cases, a battery is still required, but the control board may also have alternative power sources, like solar panels or the ability to charge via a standard household power outlet.

It's always a good idea to consult your camper fridge's manual to understand the specific power requirements of its control board and ensure you have the necessary batteries or power sources to keep your fridge running smoothly during your travels.

RV fridges work best when level

The duration for which a camper fridge can run on propane depends on the size of the propane tank and the fridge. A 20-pound propane tank can last 9 to 34 days, while a 25-pound tank can last 9 to 32 days. The duration also depends on the size of the fridge, with larger fridges consuming more propane.

Now, onto the main topic of discussion: RV fridges work best when level.

RV gas absorption refrigerators are designed quite differently from residential refrigerators. To ensure the refrigerator in your RV functions properly, your trailer or motorhome needs to be level. While tilting the RV a degree or two to drain rainwater or dew usually doesn't cause any issues, prolonged tilting can be problematic. If the fridge runs while tilted for more than 30 minutes, the refrigerator's cooling unit may be damaged. This is because RV refrigerators use gravity, instead of a compressor, to generate the heat that cools the interior. When the refrigerator is tilted for an extended period, the gravity-fed chemicals inside may stop circulating. This can lead to a build-up of ammonia crystals inside the refrigerator's tubing, which restricts or blocks the flow of ammonia liquid over time.

To prevent this issue, it is recommended to keep your RV level. For an overnight stay, having your RV within 3 degrees off level side-to-side and 6 degrees off level front-to-back is generally sufficient. However, if you plan to stay in the same spot for several days or a week, it is best to get your RV as level as possible. This will ensure optimal cooling performance and help extend the life of your refrigerator by preventing the formation of ammonia crystals.

To check the level of your RV, you can use a bubble level or even the level on your smartphone. Place it on the freezer plate inside the freezer and adjust your RV until half of the bubble is in the center circle. Additionally, if you're levelling your RV manually, consider using levelling blocks, which are an easy and quick way to achieve a level surface.

A 20-lb propane tank will last 9-34 days

The size of your fridge is not the only factor that affects how long your propane tank will last. The ambient temperature will also play a role, as the fridge will need to work harder to maintain a cool temperature when it is hotter outside. Additionally, if you are using propane for other appliances, such as a stove or furnace, this will reduce the number of days that your 20-lb tank will last.

It is worth noting that some campers have reported that their 20-lb propane tanks have lasted longer than expected. For example, one camper reported that their 20-lb tank lasted for 4 weeks while running their 3.5 cu. ft. fridge, stove, and furnace. Another camper reported that their 20-lb tank lasted for 10 days while running their 8 cu. ft. fridge, stove, and hot water heater.

If you are concerned about running out of propane, there are a few things you can do to conserve your supply. Using a separate propane grill for cooking can help extend the life of your tank, as can limiting your use of the furnace. Additionally, you can carry a backup propane tank or a smaller 1-gallon cylinder to ensure that you don't run out of propane during your trip.
