RV Refrigerator Vs. Residential Refrigerator

rv refrigerator vs residential refrigerator

Traveling for a long time in your recreational vehicle means investing in essential accessories to make it more comfortable and relaxing. Long trips require an A.C., a refrigerator, a stove, mattresses and beds, and more. You might have sorted other things but RV refrigerator Vs. Residential refrigerator might confuse you. The two types of refrigerators are efficient in their ways, but their functionality and purpose differ significantly. Hence, there is a distinct difference between the two, which we will discuss below.

RV Refrigerator


The RV refrigerator was the only type of fridge people were offered when they bought an RV until about ten years ago. Now, however, you can buy an RV with a residential fridge installed. But you will still find RVs that come with the RV refrigerator. If your RV does not have a fridge or the machine needs to be replaced, you can buy Midea’s best-selling refrigerator.

The fridge utilizes absorption to keep the inside cool. There aren’t any moving parts, such as a compressor, for operating the fridge. It employs heat, and a mixture of ammonia, water, and hydrogen gas to move through the tubes that cool the machine. The heat to power cooling gases can be given by 2 or 3 different power sources in this kind of fridge. Now let us discuss the various aspects of an RV fridge.

Storage Space

A traditional RV refrigerator has a storage capacity of 6-8 cubic feet. Class B, Class C, and travel trailer RVs are generally sold with smaller refrigerators. You will find that motorhomes and huge 5th wheels boast impressive capacity in their fridges. Newer models feature up to 18 cubic feet of space for storage and French doors. We recommend you to check with the manufacturer for their fridge specifications and request them for a large refrigerator if you want extra storage space.

Power Sources

The 2-way RV refrigerators use either LP gas or AC power to heat the gases inside tubes to cool your refrigerator. 2-way refrigerators are the most popular kinds sold in the RVs today. You may also find 3-way fridges that can run on DC power, AC power, or LP gases. They can run off 12V (volt) batteries but aren’t as popular as 2-way fridges.


RV refrigerators are made of heavy materials and specifically designed to move around in the vehicle. Such fridges don’t have compressors and other moving parts so that they do not loosen while traveling. Many recreational vehicle owners report their RV refrigerators lasting up to 20 years, which is an impressive product life for a fridge.


RV refrigerators are designed to utilize AC power, and they use propane gas to keep the inside cool if they aren’t connected to the power source. On a pleasant day, the fridge will maintain a decent temperature, while the temperature of the RV fridge may rise on warmer days.


The fridge is suitable for the families who plan to camp for several days with electric hookups available most of the time. They are also ideal for people who like to dry camp occasionally, without investing in a generator or solar panels. They work well for campers who do not require a large storage capacity. Although the models are getting better in terms of space and size, RV fridges are suitable for campers who use their rides for short periods and do not live fulltime on their trip.

The Residential Refrigerator


When you are buying an RV, you may come across options with residential fridges installed. These refrigerators use compressors to keep the insides cool and the temperatures low, and require a constant 120V AC power source. Let us learn more about them below.

Storage Space

The options will be limitless because you can find a domestic fridge in all sizes and with varying storage capacities. As compared to an RV fridge, the residential refrigerator has more space, which is one reason why campers choose residential refrigerators.

Power Source

A residential fridge requires 120V (Volt) electricity. If you are camping at a ground with 50 Amp electric hookup, this wouldn’t be a problem. But if you wish to dry camp for any period, having an alternate power source is crucial.

New RVs that feature a residential refrigerator need to have an extra inverter and battery pack installed. The inverter changes the 12V battery charge into 120V power that the fridge uses when the ride is unplugged. This feature keeps the food fresh and cool when you are driving.

Additionally, generators and solar panels act as power sources for residential fridges when they are unplugged. However, you will have to calculate the amount of energy required to keep your refrigerator running. Then, you will have to purchase energy sources accordingly.


Residential refrigerators are not designed to remain intact on the road for a long time. All the bumping will eventually affect the fridge’s life because there are many parts inside that can get damaged due to bumps. The average life of a residential fridge is up to 15 years, due to all the movement, it is less one in an RV.


Residential refrigerators keep food cool always, and their freezers keep frozen foods solidly frozen. When the fridge is not connected to the power source, it can take longer to warm up. But it maintains its temperature well. So, between RV refrigerator and Residential refrigerator, a residential refrigerator is more efficient.


RV users who wish to live in their ride for an extended period should consider a residential refrigerator. Campers who don’t mind investing a bit more initially in extra power sources like a generator, solar panels, batteries, or an inverter may choose the residential one. Lastly, a large group or family who require extra storage space while camping also wants this version.

Pros And Cons


Here is a summary of the pros and cons of RV refrigerator Vs. Residential refrigerator based on the factors discussed above. These may help you in deciding which fridge would be right for your RV. We recommend you to invest in an RV with the kind of fridge you want if you are purchasing the ride

1. RV Fridge


  • Flexible for dry camping
  • Lower investment
  • Option to run on propane gas and electricity
  • High durability


  • Smaller capacity
  • High-priced product
  • Less efficient in keeping food cold

2. Residential Fridge


  • Large space availability
  • Variety of choices
  • More efficient in keeping food cold
  • Affordable price


  • Less durable
  • Require a constant source of power or electricity
  • Higher maintenance cost
  • Requires accessories

RV Refrigerator Vs. Residential Refrigerator

Your choice from the two options will depend upon your usage, storage requirement, camping site, and budget. Although RV fridges tend to be more expensive than residential ones, they are more sturdy and have multiple power options.

On the other hand, a residential fridge has only one power source and needs an inverter to work on 12V power, which is a huge concern if you want it for dry camping. However, with generators, solar panels, and battery banks, this problem is resolved.

Residential fridges also have loose parts, which can get damaged due to jerks while driving your RV. Moreover, if you want more storage, you can buy a bigger RV fridge. However, a residential fridge is more efficient in keeping your food chilled. It is better at maintaining the temperature as well. But their product life is shorter in comparison to RV refrigerators.


It is essential to have a refrigerator in your RV if you are camping for a few days or months. While comparing RV refrigerator Vs. Residential refrigerator, it is difficult to point out which one is a winner. People who live inside their RVs with electricity supply choose to install a residential refrigerator.

Meanwhile, campers who stay at places without constant power supply will go for an RV refrigerator. The main differences between the two are mainly: power source, storage capacity, efficiency, life, and durability.

RV AC Ducted Vs Non-Ducted

rv ac ducted vs non ducted

Your recreational vehicle determines how comfortable your traveling times are. And in that, the type of AC you choose for your RV plays a crucial role. This is because the AC will make sure how properly your RV’s temperature is maintained, whether it needs maintenance, and how much power it will consume.

If you want to know in detail about RV AC ducted Vs. Non-ducted, you are at the right guide. We will be discussing the difference in their mechanisms and their suitability.

What is an RV AC?


An RV AC is amongst the essential machines that ensures the comfort of your ride. Like traditional home air conditioners, camper ACs work to reduce heat, and its purpose is to make sure your kids do not suffer from excessive heat during summer seasons.

The best RV AC should have air vents on the roof. This will enable the machine to keep your vehicle’s interior space cool efficiently. Hence, your ride maintains the desired temperatures during long drives as well. Your AC unit should have a compressor, evaporator, fans, condenser, thermostat, controls, and refrigerant systems.

Regarding how the AC works, it draws in hot air, then expels the heat outside of your RV. After that, it utilizes the vents to push cool air into your vehicle. This happens because as the cool liquid is sent to the evaporator, it absorbs heat from your vehicle’s warm air.

The liquid soaks up heat from the air as it passes through fans. As the liquid absorbs heat in the evaporator, the fluid transforms into vapor before it returns to the compressor.

There are 2 main types of camper air conditioners – ducted and non-ducted. Although the two differ in a few ways, they are similar in terms of cooling. When you select a unit, you must consider the right type, which are discussed below.

Non-Ducted RV AC 

Not all RVs feature a duct system in their ceilings, and this is why installing a non-ducted AC would be appropriate. Such RVs can be a small trailer, a Class B van, or a truck camper. Additionally, any RV with one room is likely to be ductless.

If you are renovating an old or vintage trailer that does not have an air conditioner, you must go for a non-ducted AC. Such an AC is also suitable for doing a van conversion due to its simple installation.

However, the unit has a box, which extends down from RV’s ceiling a few inches. So, the headroom is reduced, which could be a problem for taller people. The box plays a crucial role because it is where the cool air comes from.

Another factor to consider is that a ductless air conditioner creates increased humidity inside the vehicle, which forms the right environment for mold. So, if you choose a ductless AC, be sure to air out and clean the kitchen and bathroom regularly to keep the humidity under control.

Ducted RV AC

A ducted AC system has a network of ducts all over the ceiling for distributing cool air in the RV. Such a unit has multiple vents or ducts in the ceiling. These ducts are connected together with the sheet metal ducting, like a house, or, with the flexible, foil furnace duct pipe.

This kind of system means there will not be any box. Moreover, the ducts in your vehicle’s ceiling will distribute cool air through the vehicle evenly, instead of blowing it from one location.

You can also close and open the vents in the RV’s ceiling to direct the air where you want it. For instance, you can close the vents of the living room and direct all the air to the bedroom.

RV AC Ducted Vs. Non-Ducted


You might still be wondering how RV AC ducted Vs. non-ducted differentiate. Well, the basic difference is the way the two systems operate – one model uses the air ducts for directing cool airflow (ducted AC) while the other one blows air from its bottom and let cool air go wherever it wants to (non-ducted AC).

In the case of ducted AC, you can exercise better control over which parts of your vehicle receive cool air than others. The vents are also laid out systematically to make sure your entire vehicle receives even airflow. However, long air ducts may imply weaker airflow. In the case of a non-ducted air conditioner, the cool air is blown into your vehicle from a central rooftop location.

You do not lose BTUs (British Thermal Unit) or CFM (cubic feet per minute) when you have the ducted system. These elements are parts of the AC design and do not have anything to do with the duct. A 13,500 BTU AC generally puts out 300-350 CFMs. This won’t change because cool air is blown from the duct system. Also, the ducted system is a little bit more efficient because it covers all areas and does leave any hot spots.

A non-ducted AC does not ensure an even air distribution throughout your vehicle, and your RV will have cool and hot spots. But replacing a non-ducted system is easier, as you will only have to remove the existing non-duct AC and fix a new AC in its place. You must, however, be careful about connecting the wiring correctly.

If you aren’t concerned about the airflow as much as you are about the replacement and repair costs, you may opt for a non-ducted AC for your leisure vehicle. Lastly, you must know that between RV AC ducted Vs. non-ducted, the fan speeds and ability to produce cool air by the two systems are almost equal.

When Should You Go For a Ducted AC Unit?

  • Your RV already has ducts – There would be no point in installing a ductless AC if your vehicle already has ducts. Moreover, replacing the unit is way easier than changing it completely.
  • High humidity levels – A duct system is more effective in controlling the humidity inside a recreational vehicle. If you travel during monsoon season or in humid areas, a ducted AC would be more suitable.
  • Better aesthetics – A ducted AC blends well with the vehicle, and there is no box extending from its roof. So, it remains hidden behind the vehicle’s ceiling or wall.
  • Better airflow – The ducted system produces better airflow because you can direct its vents wherever desired. You can also modify them to improve the airflow.
  • Affordable repairs – Your maintenance cost is going to be lower because a ducted AC has fewer parts that break and demand repair.

When Should You Choose a Non-Ducted AC Unit?

  • Less dust – A ductless AC catches less dust as compared to a dusted one. If you suffer from dust allergy, having a non-ducted unit in your RV can avoid triggering it.
  • Smaller spaces – If there is very little room to hide vents of AC in the ceiling or walls, then you require a ductless AC.
  • Modify RV’s interior – If you love to make changes to your ride’s interior, working with a ductless system would be easier. You will not have to worry about blocking your ducted AC vents while modifying interiors if you install a non-ducted unit.
  • An additional AC – If your ride is huge or gets very hot easily, you will be requiring an additional AC, and installing a ductless system is a lot easier.


Depending on your taste, budget, requirement, and the size and type of your vehicle, your choice between RV AC ducted Vs. non-ducted will vary. In the most important factors of air conditioning, both systems match up equally. However, before choosing the type, you should remember the following differences –

  • Ductless AC will decrease headroom in your vehicle while ducted ones hide well behind the walls and ceiling of an RV.
  • You can exercise complete control over the cool air direction in the case of a ducted AC.
  • Modifying interiors and replacing the machine is easier in ductless AC.

How to Switch Propane Tanks on RV?

how to switch propane tanks on rv

It is important to always have a filled propane tank on your RV specially when you are about to go on the road. However, not many people knows how to switch propane tanks on RV or have the confidence to do it. To help with that, we have listed down below 3 easy steps on how replace your RVs propane tank.

What You Will Need


Here are the things that you need to have to do this:

  • Propane tanks

You should know where your propane tanks are located. Sometimes, you might feel lost because somebody else used to do it for you. But right now, you need to do things on your own. And the first that you need to know is the location of your tanks.

  • Filled tanks

As you are switching your propane tanks, they must have been empty already. Hence, you need to have a re-fill or just another set of propane tanks that are already filled.

  • Strength (Although, not much of it)

As guaranteed in this article, switching propane tanks on RV can be very simple. So, you do not need to have a lot of strength to do it. In fact, one thing that you must be concerned about is the weight of your tanks since you will be switching empty tanks with filled ones. Once you can manage this, there is not so much to worry about.

7 Easy Steps to Switch Propane Tanks on RV


Here are the steps on how to switch the propane tanks on your RV:

1. Remove the cover

More often than not, dual propane tanks have a cover to protect the same from dust or stains. To switch the tanks, you need to remove it first. It is not so heavy, so be careful and do it slowly but surely.

Apparently, you just need to slide it up. But before doing so, open up the lid at the top. Then, pull it up. If it does not go off quickly, then you should check if there is a strap at the bottom of the cover. It is sometimes attached to secure the placement of the cover on over your tanks.

2. Make sure that the gas is off

You wouldn’t want to cause an explosion or fire at home, at work, or in your camping site. So, after you remove the cover of the tanks, check if the gas has been turned off. It has not been turned off, then do the honors of doing so. We are definitely doing this for precaution purposes.

3. Take off the twist knobs

You can see that both of your tanks have this twist knob. Take it off from the tanks by gently twisting it to the direction that would make it come loose. Then, when it is already loose enough, disconnect the twist knobs of both tanks.

4. Disassemble

It may sound really a complicated step, but you have to know that it is simple. In the middle of both tanks, you can see that there is a huge screw that seems to hold the pole that connects the two tanks to keep them in place.

Simply rotate the wing-like screw until it gets out of the vertical pole. After doing so, remove the horizontal pole that holds the two tanks in place.

5. Re-fill tanks or switch with a filled tank

Now that you have already disassembled everything, you can now replace the tanks. After doing so, you need to re-assemble everything, just like how you did in the disassembling.

6. Re-assemble

First, you need to put the tanks in place. Then, connect the horizontal pole that holds them steady in their positions. Attach the wing-like screw to the vertical pole to lock the pole and the tanks in place. Screw back the tie knots that you have removed earlier as well. It is just an easy rotation, but make sure that you do it tight.

7. Put back the cover

As you have finished switching the propane tanks on RV, it is time to put back the cover. You surely would want to protect your tanks from unwelcome dust and stains. After putting it back on, close the lid that you have opened earlier.


See? These steps are so easy! Once you have done it for the first time, you can do it again on your own next time. You have to feel confident about it. It is not difficult at all!

How to Remove RV Roof Sealant?

how to remove rv roof sealant

As you are planning for a journey with your recreational vehicle, you want things to go as smoothly as possible. If the weather changes, you can feel secure inside the RV. Therefore, one of the first things to do is to check up your RV’s condition.

You’ve done your check-up and notice something worrisome – cracks on roof sealants. If you still want to take your chances, there is a high possibility that something will leak into your RV. To prevent problems, it is important to reseal the portions and it starts with learning how to remove the RV roof sealant.

Things to Know and Prepare


There are specific sealants used on certain types of roofing material. Knowing what sealant is used is very crucial on how to deal with them. If you have determined the sealant, then you can check what chemicals or approaches are used to remove them.

If the sealants used are reaching the end of their lifetime, they tend to crack after being hardened. You might be tempted to use a scraper but it can get messy and even damage your roof’s surface. In this article, we will not be assuming a specific roofing material, and with that, here are the things you need to prepare.

For protective equipment

  • Gloves = to safely handle tools and chemicals
  • Goggles = to prevent any foreign objects from entering the eyes

For tools

  • Scraping tools = depends on how efficient they are when used
  • Metal brush = used for further removal of hard adhesive particles
  • Degreasing agents = depends on what type of roof you are having and how sensitive it is to chemical reactions

For polishing

  • Dishwashing liquid = used to cleaning the scraped and degreased surface
  • Acetone or similar liquids = used to further polish the surface in preparation for the resealing



Step 1: Check the surroundings

If your RV is parked outside without cover, it will be better to work on a time when rain is not expected. Make sure you view the weather forecast ahead before proceeding.

If your RV is parked inside your garage, then you can safely remove the sealants anytime you want. As you are about to remove the sealants, make sure the roof is clean and no debris from the garage’s ceiling or a nearby tree is expected to fall on the surface.

Inspect the coverage of the RV’s roof to know what extent you will be working on. It is suggested to start from one side to the other so you won’t contaminate the cleaned surface.

Step 2: Apply elbow grease

Once you are ready, it is time to put on some hard labor. There are manual scrapers and motorized scrapers. Work with whatever you have, as long as it will not damage the paint or the roof’s surface.

To soften the old sealants, apply an ample amount of degreasing agent, and continue scraping. Remove the debris and check if the surfaces applied with the old sealant are spotless enough.

For areas around the bolts, a metal brush might be a better tool to scrape the sealant particles still sticking. Make sure that the roof surface will not be damaged. Once everything is rid of the old sealant, it is time to prepare for the application of a new one.

Step 3: Prepare for application of new sealant

To clean up the surfaces, use a dishwashing solution. Soak the cleaning rag or sponge and start wiping any residue left. Rinse with water and let it dry.

When it is dry enough, apply a certain amount of acetone on a certain part to be polished. Do not apply acetone or related products when it can’t be wiped directly since it will just evaporate easily.

The goal here is to polish the roof surfaces. Once you are done, have it dry totally before proceeding to apply the new sealant.


Removal of sealants of an RV seems easy enough. Although there are quite many considerations and preparations, however, the task is simple overall. You can now apply the new sealant and move on to your journey once it will be done.

Make sure you stay patient in doing the removal. Small details might affect the effectiveness of the re-application of the sealants and the state of your roof’s surface as well. The success of your work determines how your RV can survive through such unexpected weather changes.

Traveling is tiring and stressful; thus, everyone does everything to keep their road trip as less hassle as possible. If you just recently purchased your RV dinette and you wish it to be comfortable for you and your guests, here are things you need to follow to achieve that comfy road adventures:

Buy new cushions


Of course, you wanted a comfortable seat while traveling or simply have some snacks on your RV. Most RV dinette chairs are made from soft materials while some are made from wood. If your RV chair is made from the latter, you won’t surely have the comfort you desire while on a road trip. However, you can remedy the same by purchasing cushions you can sit on or you can put on your back.

If you already have cushions at home, you can just re-use it for your motor home.

There are various styles and sizes available there, and this is a wise option if you want a quick fix.

Have your cushion reupholstered

If you are on a tight budget and buying new cushions is not an option, you can reuse old cushions professionally. Buy the fabric you wanted and go to your local seamstresses to re-cover your cushions. The good thing about this is that you can personally achieve the RV dinette design that you desire. You can even request embellishment to your seamstress.

On the other hand, if you can upholster your own cushion, the better. This may not be the quickest option, but this is definitely the cheapest.

Make your RV Dinette set a sleeping bed


If you don’t use your RV dinette set for dining, transform it into an additional sleep bed. In this way, you can maximize space your motor home and, at the same time, have that comfortable snooze while traveling. Transforming your dinette into a sleeping bed is best at night or in times when you wanted to sleep while you travel.

There are special foldable RVs you can easily transform into a bed. But, if you want to DIY, you can simply put together the table and dinette chairs to form a large mattress. Very easy, isn’t it?

Put foams on your RV dinette seat

You can never escape a bumpy road while traveling. Hence, a soft seat is a must. This will require some expenditure, but this is certainly worth every penny.

Your RV dinette set is the highlight of your motor house living space. This is most likely where you will let a visitor rest once he/she visits or travel with you. For some, this can be their workspace, study area, a place to eat, or a spot to relax. Thus, comfort should be your priority when you think of designing or renovating it.

Follow this simple guide, and enjoy a comfortable adventure like no other.

How Long Will an RV Fridge Run on Battery?

how long will an rv refro run on battery

RV refrigerator is an essential appliance needed to keep foods fresh and cool while camping in RV. Me and my family always love to go on camping in an RV. Our camping experience would not be complete without a running refrigerator that stores all our food. In order for these refrigerators to run, you need batteries to power them on. But, the question is “How Long will an RV Fridge Run on Battery?”. It is highly important that we know the answer to this question so that we can do some adjustments and prepare ahead. Let us get to know the answer as we get along.

How long will an RV fridge lasts on battery?


Normally, refrigerators run using AC power. However, when you are out there camping, it is not readily available. Thanks to batteries, having a fridge in RV is still possible. With the help of an inverter, the DC from the battery will be converted to AC to power the refrigerator.

A normal residential refrigerator or an RV fridge that consumes 150 watts of power would approximately draw 12-amp hours from a 12 Volts battery. Under this circumstance, the RV refrigerator could run for about 4 to 5 hours using a single 12 Volts battery that can supply 100 amp-hours.

Most Dometic refrigerators specifically made for RV can run approximately 6 to 8 hours on a single 12 Volts DC battery.

For a smaller RV fridge that only consumes less than 70 watts of power can last up to 30 hours with a single 12 Volts battery.

What are the factors affecting the running hours of an RV fridge?


There are actually several factors affecting the number of hours an RV fridge lasts. These factors include:

  • Number of amp hours

One of the factors that affect the number of hours RV fridge lasts is the number of amp factors afforded by batteries. This means that if the battery could give more amp hours, the more hours the RV refrigerator can run.

  • Number of batteries

If you have more batteries on hand, then you can run the RV fridge for more hours. Thus, if you expect your RV fridge to run for about 6 to 8 hours with a single 12 Volts battery, then it is much better to load 2 or 3 more batteries to keep the fridge working.

  • Actual power consumption of RV refrigerator

The number of hours is also affected by the power consumption of your RV refrigerator. For instance, if you have a refrigerator that utilizes 150 watts of power, your refrigerator is only expected to last for 4 to 5 hours. On the other hand, if you are using only a 70 watts RV refrigerator, then you can enjoy more hours as compared to a 150-watts refrigerator.

This factor is also affected by the size and age of the refrigerator. With size, the larger your refrigerator the more power it consumes. As with age, the older the refrigerator the more power it also consumes.

Another factor affecting power consumption is how often you use the refrigerator. Thus, using only minimal features will yield lower power consumption.

Tips in Using battery-operated RV Refrigerator


Now, that we already have a sort of idea of how long RV refrigerators last using batteries, then here are some tips that you can use to be able to utilize these RV refrigerators for long.

  • Check the actual power consumption of your RV refrigerator

As we have said earlier, one of the factors affecting the number of hours RV refrigerator works is the power consumption of the appliance. To check the actual power consumption of your RV refrigerator, put off all the devices connected to your battery except for the fridge. Then, check the meter reading to see how many amps have been drawn. The amps drawn are on a per hour basis, so you can easily calculate how many hours your refrigerator will work.

  • Get the right battery size

One good way to prolong RV refrigerator use while boondocking is to get multiple batteries connected together. However, there are two ways to connect your battery. One is by connecting it to a series; with this, you don’t increase the amps but only the volts. For example, if you put two 6 Volt batteries, you will have 12 Volts but amp hours will not increase.

On the other hand, connecting batteries in parallel will increase the apps. If you connect batteries in parallel like two 12 Volt batteries, for instance, you will have more than 150 amps.

Therefore, you need to calculate first the power consumption of all appliances before you configure the batteries. You can connect them either in series or parallel to get the required volts or sufficient amps to keep your RV fridge working.

  • Make sure the batteries are in good condition

To ensure that you get to maximize the amp-hours the battery can give, you have to make sure that they are in good condition. Charge it accordingly as instructed. The most common reason why batteries fail is either they are undercharged or overcharged. Make sure the batteries you are going to use do not lose the charge to less than 50 percent.


When you are on a road trip or camping perhaps, a handy RV refrigerator is very important because it will store and keep your foods fresh for consumption. Thus, before you go, you have to make sure that your RV refrigerator can last throughout the whole journey. We hope this article has given you all the right insights regarding how long will an RV Fridge runs on battery and how, in a way, to prolong its use.
