Imagine RVing without heat, warm water, or the ability to cook food and store it in a refrigerator. If that were RV life, you’d be better off saving money on an expensive rig and tent camping instead. Fortunately, RVs are equipped with propane tanks, which provide the fuel needed to run essential appliances. These inconspicuous tanks are truly the unsung heroes of RV life.
Today, we’ll look at everything you need to know about an RV propane tank. Let’s get started!
What Is an RV Propane Tank?
RV propane tanks typically look similar to what you’d find on a gas grill. These tanks vary in size but function similarly. However, an RV propane system uses propane in multiple ways and makes RVing much easier and more comfortable.
Depending on the RV type, the tanks may or may not be removable. You’ll typically find non-removable tanks in large motorhomes or other motorized RVs. This means that you’ll need to find a place to take your RV to refill your tanks.
What Are the Different Types of RV Propane Tanks?
There are a couple of different types of RV propane tanks. It’s important to know which kind of tank you have on your RV. Let’s look closer at each type to identify which you have on your rig.
American Society of Engineers or ASME propane tanks are typically installed permanently on your rig. While other types of tanks use pounds for their size, these tanks use gallons. Some of the most common tank sizes range from 120 gallons to 2,000 gallons.
You’ll most commonly see these tanks at homes and other places that use propane as a heat source. However, motorhomes also often use this style of tank and mount it to the vehicle’s frame.
To have an ASME tank refilled, you could either drive your motorhome to a refill site or call a local propane supplier to come to the tank’s location.
DOT RV propane tanks are designed with mobility in mind. They’re typically smaller tanks that you’ll use to power a propane grill, portable heater, or in this case, RV appliances. Larger DOT propane tanks are available but require drivers to follow specific regulations to avoid potential risks during transport.

These tanks require certification, which lasts for 12 years from the original manufacturer date and then every five years after that. Depending on their intended use, you’ll typically find DOT propane cylinders from 5 lbs to 420 lbs.
How Much Fuel Can an RV Propane Tank Hold?
The different types of RV propane tanks use different measurements. DOT cylinders measure in pounds, while ASME tanks measure in gallons.
A gallon of propane weighs 4.24 lbs. So a 30-pound DOT RV propane tank holds approximately 7 gallons of propane. On the other hand, a 120-gallon propane tank will weigh about 420 lbs.

How Long Does an RV Propane Tank Last?
How often you use your RV propane tank greatly influences how long it lasts. If you’re using your camper on weekends only, the propane tank on your RV might last an entire camping season. However, if you’re camping full-time and often use propane to cook, heat water, cool your refrigerator, and run your furnace, you may need to refill a tank every few weeks.
Be aware of your usage so you can plan to refill your tanks before they’re empty. You don’t want to find yourself without propane and have no plan for refilling your tanks. Doing so can be a recipe for a miserable camping trip or a cold night in your RV.
Where Are RV Propane Tanks Located on a Rig?
Your RV type will likely determine where the tanks are located on an RV. Travel trailers typically house their propane tanks on the front near the jack. However, fifth wheels and motorhomes will house their propane tanks in a less visible location. Finding out where your propane tanks are located should be among your first tasks when acquiring a rig.
Do You Need an RV Propane Tank Cover?
Many travel trailers have a DOT propane tank mounted to the front of the frame. This means if it’s not covered, it’s constantly exposed to the elements while parked and driving.
Using a propane tank cover can help keep the connections and components of the propane tank free from dirt, grime, and moisture. Many RVs come with tank covers, but not all do. If you need to buy one, get the correct size to fit securely and cover it completely. Here are our recommendations: 7 Best RV Propane Tank Covers.
If your propane tank is mounted in an exterior storage compartment, it’s already protected, and you won’t need to purchase an additional cover for it.
How Do You Fill an RV Propane Tank?
Refilling propane is extremely dangerous, and only a person who has been trained should do it. As a result, you must take your propane tanks to a propane refill station or hire a propane company to come out and fill your tank. Refilling propane yourself, if not trained, may be illegal where you live.
Where Can You Fill Your RV Propane Tank?
When you need to refill, you’ll most likely need to track down a local vendor. You can start by calling local gas companies and asking if they refill propane tanks. Many of these companies sell propane in bulk and offer some of the lowest prices. However, if you can’t find a local supplier, there are other options as well.
Many hardware stores like Ace Hardware and True Value will also refill propane tanks. Rates vary from one location to the next, so ask for their price to avoid overpaying. However, if there are no supplies or hardware stores nearby, there’s one final option to consider.
Some RV parks offer propane services. If the campground you’re staying at doesn’t offer this service, you may be able to call a local RV park to see if they offer the service and inquire about costs.
Your immediate propane needs will largely determine how picky you can be when looking for a place to purchase propane. Sometimes, you just have to take what’s closest, no matter the price.
Pro Tip: Make sure you factor in the cost of propane tank fill-ups when budgeting for full-time RV life.
What Do RV Propane Tanks Power?
RV propane tanks can power most refrigerators, stove burners, water heaters, and furnaces. While it’s common for RV appliances to use propane as a power source, there may be exceptions. Check your owner’s manual and the connections to understand where your propane lines run.
If you’re on electricity, you may not need propane to power those items. Sometimes shore power or battery power can run RV appliances, except for gas stove burners. Again, check your owner’s manual if you’re unsure.
How to Maintain Your RV Propane Tank
Your RV propane tank is an integral part of your RV, so maintain it properly. You’ll want to keep all propane components and the tank itself free of dirt and debris. Give it a good cleaning every few months to avoid debris buildup.
This is also a great time to inspect the hoses and connections for leaks and secure connections to your RV. You don’t want it moving around as you travel down the road.

How Often Does an RV Propane Tank Need to Be Recertified?
Once an RV propane tank is 12 years old, you’ll have it recertified. From then on, get it recertified every five years. No one will refill your tank if it is not certified. This is because propane is extremely dangerous in the wrong circumstances, and a faulty tank could cause a dire situation.
RV Propane Tank Tips
Here are a few tips to consider when it comes to using and handling your RV propane tanks.
Keep Your Propane out of the Heat
When a propane tank sees extreme temperatures, the pressure inside the tank will build up. DOT propane tanks have safety mechanisms that allow the tank to release pressure, but you don’t want to take chances. The safest place to store your tanks is outdoors in the shade when the temperatures are cooler but not freezing.
Only Store in Vented Spaces
Storing tanks in a vented space helps prevent issues if the tanks need to release pressure. If a tank should release some pressure, propane will be released into the room. Propane is a heavy gas, so it’ll gather at the floor of a room. A large explosion can occur with even the slightest spark if propane fills the environment. Static electricity from your shoes, for example, could cause a serious explosion.
Get an Accurate Propane Gauge
Using an accurate propane gauge can help you avoid running out of propane. This can be incredibly frustrating whether you need it for cooking, heating your RV, or some other purpose. Several gauges are available; some offer Bluetooth capabilities that keep you aware of your propane level.
