Where To Refill Propane For RV?

A travel stop is one of the most typical venues to refill your propane tank. Travel and truck stations, such as Flying J and Love’s, are excellent choices. Because these stops can accommodate large vehicles, if you’re driving in a larger RV, especially one with a fixed tank, you can expect plenty of room to maneuver.

At some of the stops, you’ll just press a button to alert an attendant that you’re waiting for a propane refill outside at the fill station. You’ll simply go inside and inform them at the counter at other stops.

Retail Stores

You can fill propane at select merchants in suburban regions and some rural locations. ACE Hardware and Tractor Supply are two well-known and easily accessible possibilities.

It’s best to contact ahead in all of these circumstances since while most shops will replenish propane, not all will. You should also keep in mind that you may have to wait for a store staff who has been trained to fill propane tanks to become available. They might be new to filling propane every now and then, which could result with some extra waiting.

Small Businesses

Remote places or areas between large cities are some of the most popular RVing destinations. If you don’t want to drive all the way into town, some local businesses, such as hardware stores and petrol stations, may be able to help. If the location is popular with RVers, the demand for propane will be common, and finding it shouldn’t be difficult.

The one caveat is that the hours may be fewer than you’re used to. If at all possible, avoid visiting on weekends or in the evening. These are the most likely times you’ll see a “Closed” sign.

If you find a propane fill station but there isn’t much activity, go inside or search for instructions on the signage. In certain small towns, for example, the store owner may be working on vehicle repair in the garage rather than at the counter. When it comes to small businesses, they usually have a sign that tells you how to catch their attention.


There are propane filling stations at certain campgrounds. If you run out of propane, you can always schedule a stay at a campground that offers propane refills.

Keep in mind that this can be a more expensive option in some cases. Even if you aren’t staying at the campground, they will often sell you propane. So, if you’re in between destinations, this might still be a viable alternative.

Other Places for Removable Tanks Only

You could always make a “tank switch” at many ordinary retail locations if you have removable tanks. While this is a convenient choice, it will almost certainly be more expensive. It’s also common that the tank won’t be filled as much as it would be at a propane fill station (to allow for expansion).

At Home Depot, Lowe’s, and big supermarket chains, you can exchange your empty tank for a full one. This service is also available at many gas stations and small hardware stores.

How much does it cost to run an RV on propane?

Propane prices differ around the country. Depending on the area and method of purchase, gallon prices can range from $2.70 to $5.

The method you employ to obtain propane is also a consideration. The cost of replenishing portable tanks or aboard tanks can be significantly less than the cost of a tank swap.

If your rig has an onboard (mounted) propane tank, you’ll need to drive it to a propane depot to get it filled. You will also carry portable tanks to the refill facility if you are refilling them. This can be done in a variety of locations. The most popular are propane businesses and truck stops. Propane will cost $3 to $5 per gallon at these locations.

Many campgrounds also feature propane refill stations, which are the most convenient but can be expensive.

DOT cylinders

When you think of a propane tank, you generally think of DOT cylinders. Towable trailers like campers, fifth-wheels, and popups have these cylindrical tanks mounted vertically on the tongue or back bumper.

Because DOT tanks are not permanently attached to the RV, you may easily relocate them or swap them out. Because they are smaller, you’ll often see them in pairs on RVs.

Because they are controlled by the Department of Transportation, they are referred to as DOT tanks.

ASME RV propane tanks

The American Society of Mechanical Engineers approves and regulates ASME tanks, which are commonly found on RVs. ASME tanks, unlike DOT cylinders, are permanently attached to RVs. A single tank is normally located horizontally beneath the cabin, near to the main entryway.

RV propane tank sizes

The 20-pound and 33-pound tanks are the most frequent tank sizes, especially for DOT cylinders.

While 33-pound tanks hold more propane, 20-pound tanks are more widespread and can be found at grocery stores, petrol stations, and other locations. Tanks weighing 33 pounds are more difficult to come by, which might be problematic.

ASME tanks come in a variety of sizes because they are permanently attached to the RV. Some are as little as 20 pounds, while others may handle up to 100 gallons of propane, or 420 pounds.

What happens if the propane in your RV furnace runs out?

When you’re on the road, staying warm is one of the most important factors that define your degree of comfort. Your RV furnace’s primary function is to keep you warm. It works on gas and generates heat to keep your RV warm and cozy no matter what the weather throws at you. But what happens if the propane runs out? To provide you with the solution, we’ve combed through the most credible sources.

When a propane tank runs out, the pressure in the tank continues to decline until the RV furnace stops working completely. Allowing the gas tank to run dry can result in leaks, airlocks, rust accumulation in the tank, and broken brake lights. It’s recommended to keep your propane tank full to avoid these issues with your RV.

When it comes to this topic, there’s a lot more to learn. Continue reading to learn about the consequences of running out of propane, how to tell if your RV is out of propane, how to refuel it, and other useful information.

Is it safe to drive an RV while the propane tank is full?

When traveling, remember to turn off any appliances. Most employ an electronic ignition, which can cause a spark and an explosion if the propane line is broken. If you are an RV owner who prioritizes safety, traveling with your propane refrigerator turned off is the obvious decision.

In an RV, how long does a 20-pound propane tank last?

The first step in figuring out how long your propane tank will last in an RV is to figure out how big it is. The propane tanks in RVs are 80 percent filled. You can check your receipt to discover how many gallons were put in an empty tank if you’re filling it.

You will need to multiply the number of gallons in your tank by 91,502. The number of BTUs per gallon of propane is this.

The BTU demand of your stove, water heater, and furnace may then be determined. This information can be found in the owner’s manual or on a tag attached to the appliance. The BTU rating varies depending on the appliance.

When you add these values up, you’ll obtain your entire BTU requirement. The number of hours of propane you’ll have for the appliances you added to your calculation is calculated by multiplying this number by your total BTUs.

Because certain appliances are used more frequently than others, this figure may vary, but it will give you a fair indication of how long your gas will last.

How long does 20lb RV Propane tank last in an RV?

The length of time a 20lb propane tank will endure is determined by a number of factors. Are you in possession of a little or large RV furnace? Do you use your furnace on a regular basis? How frequently will you use your hot water tank?

When run continuously for an hour, the average-sized RV furnace will burn roughly 1/3 gallon of propane. This indicates that a 4.5 gallon propane tank in a 20-pound RV propane tank should last roughly a week.

This, too, varies depending on how frequently you use your furnace, hot water heater, and propane-powered appliances. Because of these estimates, having spare tanks or using dual propane tanks is always a good idea.

How much propane does an RV furnace use?

The RV heater, often known as a furnace, runs on propane. Follow the procedures above to establish how many hours of furnace use you have depending on the size of your RV propane tank and the BTU requirement of your furnace to estimate how much propane your RV furnace will use.

How long will a propane-powered RV refrigerator last?

The amount of propane used by your RV refrigerator is determined by its age and size. The efficiency of older models is lower. And, in general, the larger the refrigerator, the more propane you’ll need to keep it running.

Let’s take a look at a real-life scenario utilizing the Dometic Americana 8 Cu. Ft. RV Propane Refrigerator as an example.

With 8 cubic feet of internal space, the Dometic RV fridge is rated at 1500 BTUs (British thermal units) per hour. The BTUs in a gallon of propane are 91,502. So, with 1 gallon of propane, you could run your refrigerator for about 61 hours.

The length of time an RV fridge can run on propane is determined on the tank capacity. A normal 20-pound propane tank has a capacity of 4.6 gallons.

Using the aforementioned example, multiply 4.6 (gallons in a 20 lb. tank) by 61. (the hours our fridge will run off 1 gallon). A 20-pound propane tank can power an RV fridge for 280 hours, or slightly over 11 days.

Let’s take a quick look at how an RV fridge works, and then we’ll speak about how to get the most out of it. Because, while we like the notion of using our RV in remote locations, we don’t want to carry or consume more propane than we have to.

How can I tell if the propane tank in my RV is empty?

Some individuals prefer to use a propane tank weight chart to see if their tank is empty, although this isn’t always correct.

So, how much does a propane tank weigh when it’s empty? Take a look at the tare weight stamped on the propane tank’s collar/handle.

That is the only accurate way to determine the empty weight of that exact tank.

When you place a propane tank on a scale and the reading equals the tare weight stamped on the collar/handle, you know it’s empty.

If your propane tank isn’t empty, you’ll want to know how to check its level.

What is the size of a propane tank on an RV?

Propane tanks in RVs are either 20 pound or 33 pound in capacity. Because of its availability, most RVers opt for the smaller 20lb propane tank. On lengthier excursions, however, an RV with larger 33-pound propane tanks can travel longer between refills. For additional information on RV tank sizes, see the full comparison chart below.

What is the propane consumption of an RV stove?

Propane is used sparingly by RV burners. A gallon of propane has about 92,000 BTUs on average. And the average RV stove has one main burner with a BTU rating of 9000 and two neighboring burners with a BTU rating of 6500. Even if all three burners were used every day, it would take months for the average RV to require a refill.

To figure out how much propane is used, divide this by the BTU rating of the stove.

It’s impossible to establish an accurate statistic that represents actual propane usage because there are so many variables. However, a very near estimate may always be obtained, and that is sufficient.
