Where to fill your RV propane tank
You can fill an RV propane tank at propane dealers, RV supply stores, many gas stations with propane service, and some Costco locations. The most reliable option is a dedicated propane dealer — search "propane refill near me" or check the National Propane Gas Association's dealer locator on their website. Call ahead before you go, because not all locations fill RV tanks, and some have limited hours or require membership.
Gas stations that sell propane often have it outside near the pumps, but staff may need to help you connect. RV supply chains like Camping World and some regional RV dealers fill tanks on-site. Costco locations in some states offer propane refills to members at competitive prices, though availability varies widely by region.
If you are traveling and need propane urgently, call ahead to confirm the location is open and has capacity. Some dealers close during winter months or stop accepting fills when their storage tanks are full, which happens more often than you might expect.
Key Takeaways
- Propane dealers are your most reliable source and can be found through the National Propane Gas Association locator or a local search.
- You will need to know whether your tank uses a Type 1 or Type 2 valve, as some locations only fill one type.
- The fill process takes 10 to 30 minutes depending on tank size and how empty it is, and you stay with your RV during the fill.
- Bring your RV keys and be prepared to show proof of ownership or a rental agreement if you do not own the RV.
- Prices vary by location and propane market rates, so calling multiple dealers can save you money on a full tank.
What happens during a propane fill
When you arrive at a propane dealer, tell the attendant you need an RV propane fill. They will ask how large your tank is (measured in pounds, typically 20, 30, or 40 pounds for RVs) and whether it is a Type 1 or Type 2 valve. If you do not know, the attendant can look at your tank to determine this — it is marked on the valve itself.
The attendant will connect a fill hose to your tank's valve and pump propane in. You will hear the tank filling and may see frost form on the outside as the propane enters. The process takes 10 to 30 minutes depending on how empty the tank is and how fast the pump runs. You should stay near your RV during the fill in case the attendant needs to ask you questions or if something goes wrong.
Once the tank is full, the attendant disconnects the hose and may ask you to verify the connection is tight. Some dealers will hand you a receipt showing the amount of propane added and the cost. Keep this receipt — it helps you track how long a full tank lasts and can be useful if you have questions about your bill later.
Preparing your RV for a propane fill
Before you go to a propane dealer, turn off all propane appliances in your RV — your stove, water heater, furnace, and refrigerator if it runs on propane. This is a safety requirement at most dealers and prevents propane from flowing backward into your appliances during the fill.
Locate your propane tank and note its size. Most RV tanks have a label showing the capacity in pounds. If you cannot find it, the attendant can read it from the tank itself. Know whether you own the RV or are renting it, because some dealers ask for proof of ownership or a rental agreement before filling a tank.
Check that your tank's valve is not leaking. If you smell propane around the valve or see frost forming when the tank is not being filled, tell the dealer before they connect the hose. A leaking valve is a safety hazard and the dealer may refuse to fill the tank until it is repaired.
Understanding propane tank valves and safety
RV propane tanks have two common valve types: Type 1 and Type 2. A Type 1 valve has a straightforward on-off knob and is the older standard. A Type 2 valve (also called an OPD valve, for overfill protection device) has a spring-loaded mechanism that stops the fill automatically when the tank reaches 80 percent capacity. This prevents the tank from rupturing if propane expands in heat.
Most modern RVs have Type 2 valves, and most propane dealers now fill only Type 2 tanks for safety reasons. If your RV has an older Type 1 valve, you may have difficulty finding a dealer willing to fill it. Some dealers will retrofit your valve to Type 2, which costs money but makes future fills easier and safer.
Never attempt to fill a propane tank yourself or have someone without propane certification do it. The process requires specialized equipment and training to prevent leaks, overfilling, and other hazards. Dealers are licensed and insured for this work.
How much a propane fill costs
Propane prices fluctuate based on market rates and your location. Rural areas typically pay more than cities because propane must be transported farther. Winter prices are often higher than summer prices because demand increases. A full 30-pound tank might cost anywhere from $25 to $60 depending on these factors, but this range varies significantly by region and season.
Some dealers charge by the pound of propane added, while others charge a flat fee per fill. Ask the dealer their pricing structure before they fill your tank so you know what to expect. Costco locations often have lower per-pound prices than independent dealers, but membership is required and availability is limited to certain states.
Keeping track of how much propane you use helps you budget for future fills. Note the date and amount added each time you fill, then track how long that propane lasts. This gives you a sense of your usage rate and helps you plan refills before your tank runs empty.
What to do if you cannot find a propane dealer nearby
If you are in a remote area or traveling and cannot locate a propane dealer, call a local RV park or campground. They often have propane on-site or can direct you to the nearest dealer. RV parks are accustomed to helping travelers find services and usually have current information about which dealers are open and accepting fills.
Some RV supply stores offer mobile propane service, meaning they will come to your RV location to fill your tank. This costs more than a dealer fill but can be worth it if you are stranded or unable to drive to a dealer. Search online for "mobile propane RV" plus your location to see if this service is available.
If your tank is completely empty and you cannot reach a dealer, you may need to stay at an RV park or campground for a night or two until you can arrange a fill. Plan ahead during long trips to avoid running out of propane, especially in winter when demand is high and some dealers close or run low on supply.
Frequently Asked Questions
Can I fill my propane tank at a regular gas station?
Some gas stations have propane pumps outside, but not all fill RV tanks. Many are set up only for small grill bottles or vehicle propane systems. Call ahead to confirm the station fills RV propane tanks and ask what valve types they accept.
How often do I need to fill my propane tank?
This depends on how much you use propane for heating, cooking, and hot water. A 30-pound tank might last two weeks to two months depending on season and usage. Track your fills to learn your own usage pattern and plan refills accordingly.
What if my propane tank has not been filled in over a year?
Tanks that sit unused for long periods may need inspection before refilling. Some dealers require a safety inspection or recertification. Call ahead and describe your situation so the dealer can tell you what paperwork or inspections are needed.
Do I need to be present when my RV propane tank is filled?
Yes. You must stay with your RV during the fill so you can answer questions about the tank and respond if any issues arise. The attendant may also need your keys to access the propane compartment or to start the RV if they need to check connections.
Can I fill a propane tank that belongs to a rental RV?
Yes, but bring your rental agreement with you. Some dealers ask for proof that you have permission to fill the tank. The rental company may also have specific dealers they prefer or require you to use, so check your rental paperwork before you go.
