2. Flame King YSN5LB 5 Pound Propane Tank Cylinder
The FLAME KING YSN5LB is the ultimate portable solution for RVers and campers, perfect for fueling small, standalone appliances like portable grills, fire pits, or heaters. This compact 5-pound tank is built from high-grade, welded steel with a corrosion-resistant powder coating. It features a lightweight design and an easy-to-hold collar, making it exceptionally portable for activities like tailgating or ice fishing.

Performance is reliable for its size, providing hours of use for smaller applications, though the limited capacity means it is not suitable for running a primary RV furnace or larger appliances. For enhanced convenience, this model even includes a **built-in gauge**, a feature often missing on smaller tanks.
This little Best RV Propane Tanks unit is best suited as a secondary, highly portable fuel source for outdoor cooking and auxiliary heating.

3. Flame King YSN-301 30 Pound Steel Propane Tank Cylinder (White)
Essentially identical in core performance to its standard counterpart, the Flame King YSN-301 in white offers the same great 30-pound capacity with a slightly different aesthetic and connection type. Built from robust, high-grade welded steel with a powder-coated exterior, this large tank is designed to be the primary, reliable propane source for large RVs and long trips. It features the essential Overfill Prevention Device (OPD) valve, complying with safety regulations required for refilling in most states. This model’s key difference is its connection type—featuring two flange ports, which some RV systems may prefer or require, and provides versatility for hookup.
Furthermore, the tank provides excellent performance, delivering consistent fuel flow to furnaces, stoves, and water heaters. Safety is confirmed by X-ray and hydrostatic testing, alongside DOT and Transport Canada certification. While the primary benefit remains the extended time between refills, the tank’s dimensions (12 x 12 x 24 inches) and substantial weight when full mean it’s intended for fixed mounting on the RV tongue or dedicated external compartment.

Overall, this is a heavy-duty, reliable option among Best RV Propane Tanks for serious RVers who need maximum capacity and a certified, safe design. The dual-flange connection and white finish make it a niche alternative to the black version, particularly appealing for users prioritizing high-visibility safety or specific plumbing requirements. If you have the space and need for 30 pounds of propane, this Flame King model provides dependability, but confirm the flange connection type meets your RV’s needs.

4. Flame King YSN230b 20 Pound Steel Propane Tank Cylinder with Built-in Gauge
The Flame King YSN230b is the common workhorse of the propane world, offering a balanced 20-pound capacity that suits most moderate RVers and is widely accepted for exchange or refill. Its key selling point is the built-in gas meter gauge, which accurately provides real-time gas level readings—a fantastic feature that eliminates the frustration of unexpectedly running out of fuel. Built with high-grade, powder-coated steel, this tank is designed for longevity and rust prevention, ensuring it holds up well when mounted externally on an RV. This versatile tank is ready for grilling, camping, and general RV heating needs.
Performance-wise, the 20-pound size strikes a sweet spot between capacity and portability, making it significantly easier to handle and transport than a 30-pound tank. Like all quality models, it includes an essential OPD valve for overfill prevention and is DOT certified for safety.

A minor drawback is that while the gauge is highly convenient, like most pressure-based gauges, its accuracy can fluctuate slightly with temperature changes, though it remains immensely helpful compared to having no gauge at all.
The Flame King YSN230b is one of the most practical and convenient Best RV Propane Tanks available, especially for those who despise the guesswork of fuel levels. It’s perfectly sized for RV owners who prioritize a balance of capacity and portability, and the built-in gauge offers peace of mind. For a standard primary or secondary RV tank, this model’s blend of capacity, features, and safety is difficult to beat.

5. Flame King 10LB Steel Propane Tank Cylinder with Type 1 Overflow Protection Device Valve
The Flame King 10LB tank serves as an excellent mid-sized option, offering more fuel than a small 5-pound tank but with greater portability than a 20-pound unit. It’s often referred to as an “11-pound” tank in the industry but holds an accurate 10.51 lbs—perfect for longer grilling sessions, dedicated patio heaters, or use as a robust auxiliary tank on an RV. Built with high-grade steel and a durable powder coat, this cylinder is designed for long-term refill use, making it an environmentally and economically sensible choice. It includes the mandatory OPD valve and is DOT approved for safety and legal transport.
Furthermore, the tank is X-ray and hydrostatic tested, ensuring quality and reliability for use with various appliances during camping and overlanding. Due to its size, it easily fits into smaller RV storage areas or truck camper setups where a standard 20-pound tank is too large. Performance is consistent, providing sufficient fuel for moderate-draw appliances. One minor consideration is that, like most tanks in this capacity range, it does not include a built-in gauge, requiring a separate in-line gauge if you wish to monitor the fuel level actively. This model is pre-purged and ready for its first fill, getting you into action faster.
Ultimately, this Best RV Propane Tanks option is a fantastic choice for RVers needing a highly capable auxiliary tank or a primary tank for a smaller setup like a van conversion.

In summary, the YSN201b represents a dependable, no-frills option in the Best RV Propane Tanks category.

7. Flame King YSN201HZL 20-LB Steel Horizontal Propane Tank Cylinder
For RVs, truck campers, or fire pit tables with specific space constraints, the Flame King YSN201HZL offers a vital solution: a horizontal 20-pound propane tank. While most tanks are vertical, this low-profile design allows it to fit snugly into compartments where height is an issue, a common scenario in many modern RV designs.

Ultimately, the YSN201HZL is a niche but necessary product among Best RV Propane Tanks for those with dedicated horizontal storage. It solves a specific mounting problem while still providing the standard 20-pound capacity and desirable features like the built-in gauge. If your vehicle or appliance setup requires a low-profile design, this certified and feature-rich horizontal tank is an excellent and safe investment.

8. Flame King YSNR501 50 Pound Refrigerant Recovery Cylinder Tank
The Flame King YSNR501 is a refrigerant recovery cylinder, distinct from a standard propane tank, making it a highly specialized item.

How to Choose Best RV Propane Tanks
Selecting the appropriate propane tank is vital for a safe and comfortable RV experience. The Best RV Propane Tanks are essentially pressurized steel cylinders used to store the liquid petroleum gas that powers your RV’s furnace, water heater, refrigerator, and cooking appliances. They are for any RVer, from weekend warriors to full-time travelers. Choosing the right one matters because capacity dictates how often you need to refill, and safety certifications (like the OPD valve) are mandatory for legal use and refilling. Furthermore, tank quality ensures durability and integrity, especially when exposed to varying weather and road conditions.
Tank Capacity (e.g., 5 lb, 20 lb, 30 lb)
Capacity, measured in pounds (lbs), is the most critical factor. It dictates the volume of propane a tank can hold, directly impacting how long it will last. For example, a 20-lb tank is standard for most RVs and grills, while a 30-lb tank provides more fuel for extended trips. Evaluate your needs: a small 5-lb tank is great for auxiliary grilling, but a 30-lb tank is better for primary use. Consider the size of your RV’s dedicated storage and how frequently you want to refill before purchasing your Best RV Propane Tanks.
Overfill Prevention Device (OPD Valve)
The Overfill Prevention Device (OPD) is a non-negotiable safety feature, required by law in many regions for tanks up to 40 pounds. The valve’s purpose is to automatically shut off the flow of gas when the tank reaches approximately 80% capacity, leaving a crucial air space for the liquid propane to expand safely as temperatures rise. Always ensure the tank you purchase has this valve, often indicated by a triangular handwheel. Without an OPD valve, most reputable propane dealers will refuse to refill your tank due to safety concerns.
Construction and Finish
The tank’s material should be high-grade welded steel for maximum durability and pressure integrity. The finish, typically a durable powder-coating, is essential for resisting rust and corrosion from moisture and road salt. Look for coatings that are resistant to chipping. A quality finish extends the life of your Best RV Propane Tanks, a critical factor since tanks have a limited lifespan (usually 12 years before re-certification is needed). Better construction means better resilience against the elements and road vibration.
Certification and Compliance
Propane tanks must meet strict regulatory standards for safe transport and use. Always check that the tank is DOT (Department of Transportation) certified in the US and/or Transport Canada (TC) certified in Canada. These certifications mean the tank has been rigorously tested (X-ray and hydrostatic testing) and adheres to manufacturing and safety protocols. Purchasing an uncertified tank is unsafe and will prevent you from having it legally filled at most commercial locations. Ensure your tank is stamped with the appropriate compliance markings.
Portability vs. Stationary Use
Decide whether your tank will be permanently mounted to your RV or frequently moved for external use (like a grill). Smaller tanks (5lb, 10lb) are highly portable for cooking away from the RV. Larger tanks (30lb, 40lb) are typically stationary, mounted on the RV tongue or in a compartment, and are heavy when full. If portability is a concern, consider models with built-in handles or carrying collars. This also relates to finding the right best RV propane tank covers to protect your fixed tanks.
Understanding RV Propane Tank Life and Maintenance
Propane tanks, even the Best RV Propane Tanks, don’t last forever. DOT regulations require tanks to be re-qualified or replaced 12 years after the manufacture date stamped on the collar. The re-qualification process involves hydrostatic testing by a certified inspector. Additionally, proper maintenance is crucial. Always inspect the tank body and valves for rust or damage before refilling. Keep the tank clean and ensure the valve is tightly closed when not in use. Propane tanks should always be stored and transported vertically to ensure the OPD valve functions correctly and prevent liquid withdrawal, which can lead to dangerously high pressure and flow rates. Always refer to a reliable source for propane safety tips before handling or transporting gas.
How to Use Best RV Propane Tanks
- Step 1: Setup/prep – Ensure the tank is securely mounted (if fixed) or placed on a level, stable surface. Check that the tank is certified and not expired. Confirm the OPD valve handwheel is fully closed.
- Step 2: Core usage & best practices – Connect the regulator hose securely to the tank’s valve. If it’s a Type 1 connection, the hose will tighten by turning it counter-clockwise (opposite of a typical thread). Slowly open the tank valve all the way, then check all connections for leaks using a soapy water solution (bubbles indicate a leak).
- Step 3: Optimization/safety/maintenance – Never store spare tanks inside the living area of the RV. When replacing tanks, ensure you choose a quality product that fits your storage and capacity needs, such as finding the right size for van life cooking setups. Always close the main tank valve when the RV is in motion or when an appliance is not in use for an extended period.
- Step 4: Troubleshooting & pro tips – If propane flow stops suddenly, close the tank valve, disconnect, and reconnect it. This often resets the excess flow valve (a separate safety device that senses a sudden large leak and shuts off flow). Always refill tanks at certified locations; do not use non-certified tank-to-tank transfer devices.
Frequently Asked Questions
What is the typical lifespan of Best RV Propane Tanks?
A standard steel Best RV Propane Tanks model is certified for 12 years from the date of manufacture. After 12 years, it must be inspected, hydrostatically tested, and re-certified by a licensed professional for continued use. Most tanks can be re-certified several times, often extending their lifespan substantially past the initial 12 years.
Can I use a vertical propane tank horizontally?
No, you should never use a vertical Best RV Propane Tanks model horizontally. Vertical tanks draw vapor from the top space, while horizontal tanks have a dip tube that draws vapor from the highest point when laid down. Using a vertical tank horizontally will draw liquid propane, which can damage appliances and create a highly dangerous situation due to unregulated pressure.
What does OPD mean on a propane tank?
OPD stands for Overfill Prevention Device. It is a mandatory safety mechanism on most Best RV Propane Tanks up to 40 pounds. The OPD valve automatically prevents the tank from being filled beyond approximately 80% capacity, leaving room for the liquid propane to safely expand as its temperature increases. This prevents dangerous pressure build-up.
Is it cheaper to exchange or refill Best RV Propane Tanks?
It is almost always cheaper to refill Best RV Propane Tanks than to exchange them. Exchange programs charge you a premium and only fill the tank to about 75-80% capacity (which is safe practice, but less total fuel). Refilling allows you to pay only for the volume of gas you need and ensures you get the most value from your fuel.
What size Best RV Propane Tanks should I choose for a small travel trailer?
For a small travel trailer, the 20-pound tank is typically the most versatile choice. It offers enough fuel for several days of continuous use, strikes a good balance between capacity and weight, and is the most common size, making it easy to find refills or exchanges anywhere you travel.
Final Thoughts
Choosing the right Best RV Propane Tanks is a crucial decision that impacts your safety, convenience, and time on the road. The most important factors are ensuring the tank has the mandated OPD valve and is DOT-certified. From there, your choice comes down to capacity (30-pound for long stays, 20-pound for balance, 5/10-pound for auxiliary use) and useful features like built-in fuel gauges. Investing in quality, certified tanks protects your rig and allows you to enjoy worry-free travels for years to come.
For most buyers, the Flame King YSN230b 20 Pound Tank with Built-in Gauge offers the best balance of performance and value due to its convenient size and essential fuel monitoring feature. If you need maximum capacity for extended boondocking, choose the Flame King YSN-301 30 Pound Steel Propane Tank for its robust construction and extended run time.
