The ideal propane tank size for your travel trailer depends largely on your camping style, the number of propane appliances you use, and the duration of your trips. While a standard 20-pound (5-gallon) propane tank might suffice for weekend getaways with minimal propane appliance usage, longer trips or frequent use of propane-powered appliances like refrigerators, furnaces, and water heaters often necessitate a larger capacity, such as a 30-pound (7.5-gallon) or even two 20-pound tanks.
Understanding Your Propane Needs
Determining the right size propane tank for your travel trailer isn’t a one-size-fits-all answer. It requires careful consideration of several factors, including your camping frequency, the types of appliances you use, and the climate you’ll be camping in.
Assessing Your Appliance Usage
The first step is to identify all the propane-powered appliances in your travel trailer. Common examples include:
- Furnace: Often the biggest propane consumer, especially in colder climates.
- Refrigerator: Can run continuously on propane, impacting consumption significantly.
- Water Heater: Requires propane to heat water for showers and washing dishes.
- Stovetop/Oven: Usage depends on cooking habits.
- Grill: If connected to the trailer’s propane system.
Once you’ve identified your appliances, understand their BTU (British Thermal Unit) consumption. This information is usually found on the appliance’s data plate or in the owner’s manual. Higher BTU ratings indicate greater propane consumption.
Considering Your Camping Style
Are you a weekend warrior or a long-term traveler? Do you prefer to boondock (camp without hookups) or stay at campgrounds with full amenities? Boondocking necessitates greater propane reliance for essential functions like heating and refrigeration, while campgrounds with hookups may reduce your propane consumption, as you can often use electricity for these purposes.
Factoring in Climate and Season
Cold weather significantly increases propane consumption due to the need for furnace operation. Conversely, warmer weather reduces the need for heating, minimizing propane usage. Plan accordingly based on the expected climate conditions during your trips.
Propane Tank Sizes and Capacities
Propane tanks for travel trailers come in various sizes, each with different capacities and benefits.
- 20-pound Tank (5-Gallon): This is the most common size, readily available and relatively lightweight. It’s suitable for shorter trips or situations where propane usage is minimal.
- 30-pound Tank (7.5-Gallon): A larger capacity tank provides extended runtime for appliances, ideal for longer trips or more frequent propane appliance use.
- 40-pound Tank (10-Gallon): Less common but offers even greater capacity for extended boondocking adventures.
- Horizontal Tanks: Often permanently mounted on the travel trailer’s frame, offering larger capacities and convenient refueling. These are typically measured in gallons and can range from 20 to 100 gallons.
Benefits of Multiple Tanks
Consider using two or more 20-pound tanks instead of a single larger tank. This offers several advantages:
- Flexibility: Easier to transport and refill individual tanks.
- Convenience: Allows you to swap tanks when one runs out, providing uninterrupted propane supply.
- Redundancy: Ensures you always have a backup supply of propane.
Choosing the Right Size
The best way to determine the right size is to estimate your propane consumption. Keep a log of your propane usage during a typical trip to understand your needs. If you consistently empty a 20-pound tank during a weekend trip, upgrading to a 30-pound tank or using two 20-pound tanks is advisable.
Consider the weight of the tank when full. Propane weighs approximately 4.2 pounds per gallon. A full 20-pound tank weighs around 37 pounds, while a full 30-pound tank weighs around 56 pounds. Factor this into your travel trailer’s weight capacity.
Frequently Asked Questions (FAQs)
1. How long will a 20-pound propane tank last in a travel trailer?
The lifespan of a 20-pound propane tank depends entirely on the usage of your appliances. Running the furnace continuously in cold weather can deplete a tank in a day or two, while minimal use of the stovetop and refrigerator might allow it to last for a week or more.
2. Can I run my RV refrigerator solely on propane?
Yes, most RV refrigerators are designed to operate on propane, electricity (120V AC or 12V DC), or both. Operating solely on propane is common when boondocking or when electricity is unavailable.
3. Is it safe to travel with propane tanks connected?
Yes, it’s generally safe to travel with propane tanks connected, provided they are properly secured and the system is leak-tested regularly. Regulations may vary by state or province, so check local laws.
4. How do I check the propane level in my tank?
Several methods exist. You can use a propane tank gauge, weigh the tank (subtract the tare weight stamped on the tank), or pour hot water down the side and feel for a temperature difference – the level of the propane will be where the tank feels cold.
5. What is the difference between OPD and non-OPD propane tanks?
OPD (Overfill Protection Device) valves are safety valves required on all refillable propane tanks manufactured after October 1, 1998. They prevent overfilling, which can be dangerous. Non-OPD tanks are older and should be replaced with OPD-equipped tanks.
6. Can I refill my own propane tank?
While possible with specialized equipment and training, it is generally not recommended due to safety concerns and potential legal ramifications. It’s best to have your tanks professionally refilled at a qualified facility.
7. What are the signs of a propane leak?
The most common sign is a rotten egg smell. Propane is naturally odorless, so a chemical odorant is added to make leaks detectable. You may also hear a hissing sound near the tank or connections. Soapy water applied to connections can reveal leaks by forming bubbles.
8. What should I do if I suspect a propane leak?
Immediately turn off the propane supply at the tank. Extinguish any open flames or sources of ignition. Open windows and doors to ventilate the area. Do not use electrical switches or devices that could create a spark. Contact a qualified propane technician to inspect and repair the system.
9. How often should I have my propane system inspected?
It’s recommended to have your propane system inspected annually by a qualified technician to ensure its safe and proper operation.
10. Can I use a propane adapter to connect a smaller appliance to my RV propane system?
Yes, adapters are available to connect smaller appliances like portable grills or heaters to your RV’s propane system. Ensure the adapter is compatible with your system and the appliance, and follow all safety precautions.
11. What is the ideal pressure setting for my propane regulator?
Typically, travel trailer propane regulators are set to a pressure of 11 inches Water Column (WC). Consult your appliance manuals for specific pressure requirements. Using the wrong pressure can damage your appliances.
12. Where can I find propane refueling stations?
Propane refueling stations are widely available at RV parks, campgrounds, gas stations, and propane supply companies. Online directories and apps can help you locate nearby stations.
By carefully considering these factors and understanding your propane usage, you can select the optimal propane tank size for your travel trailer, ensuring a comfortable and worry-free camping experience. Remember to prioritize safety and regularly maintain your propane system for optimal performance and peace of mind.
