5 Best Portable Propane Tanks For RV Cooking For True Self-Reliance
The right tank means cooking freedom on the road.
You found the perfect boondocking spot. The view is incredible, the solitude is absolute, and you’re miles from the nearest town. Then you glance at your RV’s propane gauge—it’s hovering near empty. Suddenly, your off-grid paradise feels a lot less secure.
This is the moment every RVer dreads. Your main tanks power your furnace, your water heater, and your fridge. Running them dry for the sake of your outdoor grill is a rookie mistake, one that can turn a dream trip into a logistical nightmare. True self-reliance isn’t just about having enough fuel; it’s about having the right kind of fuel system.
A dedicated, portable propane tank is the answer. It decouples your outdoor cooking and comfort from your rig’s essential systems. It’s your backup, your extension, and your ticket to staying off-grid longer with total peace of mind.

Why Your RV Needs a Portable Propane Tank
This 6-pack of 16 oz propane cylinders offers convenient, ready-to-use fuel for all your outdoor adventures. Made in the USA from durable steel, they fit most standard camping grills and lanterns for versatile cooking.
Your RV’s onboard propane tanks are the heart of your rig, but they have one major limitation: they are attached to the vehicle. To refill them, you have to pack everything up and drive your entire home to a propane station. A portable tank completely severs that link.
This separation creates incredible flexibility. You can power a Blackstone griddle, a portable fire pit, or a buddy heater well away from your rig without draining your primary supply. This strategy preserves your onboard propane for the critical systems—keeping your food cold and your interior warm. It’s about creating redundancy.
Cook restaurant-quality meals anywhere with this 28-inch Blackstone flat top griddle. Its 470 sq. in. cooking surface and rear grease management system make preparing everything from breakfast to steak effortless. Easily transportable with foldable legs and caster wheels, it's perfect for your backyard or campsite.
Ultimately, a portable tank is an investment in freedom. It allows you to extend your stay, cook without worry, and handle an unexpected fuel shortage without derailing your entire trip. It transforms your fuel supply from a single point of failure into a resilient, adaptable system.
Flame King 5 lb: Your Compact Cooking Companion
The 5 lb tank is the logical, sustainable upgrade from those wasteful 1 lb green canisters. It’s small, lightweight, and incredibly easy to handle. For solo travelers or weekend warriors with limited storage, this little tank is a game-changer.
Think of it as your dedicated grilling partner. It holds enough fuel for numerous cookouts on a portable grill or camp stove. It’s perfect for setting up a quick outdoor kitchen for a few days without ever touching your main tanks.
Enjoy perfectly cooked food on the go with this portable 14-inch charcoal grill. Its 3-point locking lid preserves heat, while the dual venting system ensures consistent airflow for even cooking.
The trade-off is obvious: capacity. You’ll be refilling a 5 lb tank more often than its larger cousins. But for its sheer portability and low cost of entry, the Flame King 5 lb tank provides immense value, making disposable cylinders obsolete.
Worthington 11 lb: Extend Your Off-Grid Stays
For many RVers, the 11 lb tank is the undisputed sweet spot. It strikes the perfect balance between fuel capacity and manageable portability. It’s big enough to last a week or more of heavy use but isn’t a back-breaker to move around camp.
This is the workhorse tank for the serious boondocker. It can run your grill for dinner, your fire pit for the evening, and still have plenty of fuel left for morning coffee. Its "squat" profile is also a major advantage, offering better stability on uneven ground and fitting neatly into most RV storage bays.
While heavier than a 5 lb tank, the 11 lb size dramatically reduces the frequency of your refill trips. It provides enough propane to feel secure on longer trips without the bulk and weight of a full-size 20 lb tank. It’s the versatile choice for those who want capacity without sacrificing convenience.
Viking 17 lb: See Your Fuel, Shed the Weight
Steel propane tanks have two fundamental flaws: they are heavy, and you can’t tell how much fuel is inside. Composite tanks, like the Viking 17 lb, solve both problems brilliantly. Made from a durable, translucent fiberglass material, they are significantly lighter than steel.
The real magic is the ability to see the liquid propane level. This completely eliminates the guesswork and the dreaded mid-cookout flameout. You know exactly when you need a refill, which is a massive advantage for planning and peace of mind when you’re far from services.
The primary drawback is the upfront cost, as composite tanks are more expensive than steel. They also look different, which can sometimes confuse new refill station attendants. But for those who prioritize a lightweight setup and the certainty of a visual fuel gauge, the Viking is an investment in convenience and confidence.
Ignik Gas Growler: Your Rugged, All-in-One Kit
Enjoy portable, eco-friendly grilling with the Ignik Refillable Gas Growler. This 5-pound propane tank includes a 4-foot adapter hose and a durable carry case, perfect for camping, RVing, and tailgating.
The Ignik Gas Growler isn’t just a tank; it’s a complete, field-ready system. It packages a 5 lb tank inside a rugged, insulated carrying case that includes a 4-foot hose and adapter. This is the grab-and-go solution for adventurers.
This kit is designed for the realities of life on the road. The protective case prevents dings and scratches while bouncing around in a truck bed or storage bay. It also makes carrying the tank and hose a simple, one-handed operation, streamlining your setup and teardown process.
You’re paying a premium for a curated kit, but the value is in its thoughtful design and durability. For RVers who move frequently and demand gear that is both tough and efficient, the Ignik system removes friction from the daily routine of setting up camp.
Manchester 20 lb: Your Long-Term Fuel Solution
The standard 20 lb propane tank is the most recognizable and widely available option on the planet. You can refill it almost anywhere or, in a pinch, exchange it at thousands of gas stations and grocery stores. That universal availability is its superpower.
This isn’t your everyday portable tank; it’s a semi-permanent fuel depot. For long-term boondockers or those who set up a basecamp for weeks at a time, the 20 lb tank is an unbeatable bulk storage solution. It can power an entire outdoor kitchen and multiple appliances without needing a refill for a very long time.
Its size and weight are its biggest liabilities. A full 20 lb tank weighs nearly 40 pounds, making it cumbersome to move. But if your priority is maximum fuel longevity and you don’t need to move the tank often, the classic 20-pounder remains the king of capacity.
How to Choose Your Perfect Portable Propane Tank
There is no single "best" tank, only the best tank for your specific travel style. Your decision should be based on a clear-eyed assessment of how you camp. The choice comes down to balancing three key factors.
Start by weighing your needs across these categories:
- Capacity vs. Portability: Are you a weekend warrior or a full-timer? A 5 lb tank is great for short trips, while a 17 or 20 lb tank is better for extended stays. Consider not just how much fuel you need, but how much weight you’re willing and able to lift and store.
- Material & Features: Steel is the economical, durable standard. Composite is a premium upgrade for those who want a lighter tank with a built-in visual fuel gauge. Decide if the extra cost is worth the convenience.
- Primary Use Case: Will this tank only power a small grill, or will it be running a high-output griddle and a propane fire pit simultaneously? Your expected consumption is the most critical factor in choosing the right size.
Don’t just buy the biggest tank you can find. A massive, half-used tank taking up valuable space is just as inefficient as a tiny tank that’s always empty. Match the tank to your reality.
Our Final Verdict on Your Best RV Propane Choice
The goal of a portable propane tank is to increase your self-reliance by building redundancy into your systems. It’s not about replacing your onboard tanks but supplementing them intelligently. The right choice gives you options when you’re off the grid.
For the vast majority of RVers, the 11 lb steel tank represents the ultimate compromise. It holds more than double the fuel of a 5 lb tank, making it practical for week-long trips, yet it remains significantly lighter and more compact than a 20 lb tank. It’s the versatile, do-it-all option that fits the needs of most boondockers.
Ultimately, your RV is a vehicle for exploration. The right gear should fade into the background, working reliably to remove limits and reduce anxiety. A well-chosen portable propane tank does exactly that, ensuring you can focus less on logistics and more on the view from your campsite.
Choosing the right portable propane tank is a small decision that has a huge impact on your freedom and comfort on the road. It’s the key that unlocks longer, more confident stays in the wild places you love. It transforms your RV from just a vehicle into a truly self-sufficient basecamp, ready for whatever adventure comes next.
