Why Dual 1 lb Propane Tanks Beat Big, Heavy Single Tanks for Overlanding

Convenience is King!

When you’re living out of a rig, fuel isn’t just “fuel” — it’s heat, hot meals, coffee, and light. For a lot of trips, dual 1 lb propane cylinders outperform a single big tank because they’re lighter, easier to stash, and give you redundancy instead of a single point of failure.

Here’s what the camping community says, how the numbers pencil out, and how a purpose-built mount turns 1 lb bottles into a clean, rattle-free system.

What Campers Actually Say about 1LB Bottles

Across camping forums and Reddit, people highlight three recurring benefits: grab-and-go convenience, easy storage, and broad compatibility with stoves, lanterns, heaters, and small grills.

  • “I move the Q [grill] around, so I’m likely to stay with the small bottles… it’s convenient to keep a small inventory.” 
  • “Any hardware, sportswear… even Target probably sells them.” 
  • “Use mine for stoves and lanterns… portable grill…” 
  • Many van and RV users routinely carry several 1 lb cylinders without issue, noting DOT approval for transport when used as intended. 
  • On trip length, users report a single 1 lb can covering several meals on a weekend — enough that they bring a spare more for peace of mind than necessity. 

The portability math: weight and bulk

Weight is where small cylinders shine.

  • A typical 1 lb (16 oz) propane cylinder weighs ~2 lb total when full. 
  • A 5 lb tank is roughly 15 lb full (≈ 9–10 lb empty + 5 lb propane). 
  • A 20 lb tank is ~37–39 lb when full. 
Two full 1 lb bottles are ~4 lb total vs ~15 lb for a 5 lb or ~37 lb for a 20 lb. For rigs where every pound and cubic inch matters, dual 1 lb bottles are easier to place low and out of the way.

Redundancy beats single-point failure

With two independent cylinders, an empty or faulty bottle doesn’t kill your kitchen. You simply swap to the second and keep cooking. Our Dual 1LB Propane Tank Mount is purpose-built around that idea — it includes a selector indicator so you can deliberately run one bottle to empty before switching, avoiding a drawer full of mystery half-used cans. 

Resupply anywhere

One reason 1 lb bottles are popular: you can find them almost anywhere — hardware stores, outdoor retailers, farm stores, even big-box chains — making road-trip resupply easy. 

Sustainability is getting better for 1 lb use

Single-use 1 lb cylinders create waste, and several states are pushing changes. California will ban sales of single-use 1 lb cylinders by 2028; national retailers are rolling out refillable-exchange programs to reduce waste and keep the convenience. 
 
Important safety note: do not refill disposable DOT-39 cylinders — federal guidance and propane suppliers warn it’s illegal and dangerous. If you want refillable, use DOT-certified refillable 1 lb cylinders (e.g., Flame King or Mr. Heater Fuel Keg, Ignik bottles coming in October 2025). 

How the AAL Dual 1 lb Propane Tank Mount makes small bottles “trail-ready”

Our mount addresses the two real annoyances of 1 lb bottles — securing them and managing them.
  • Trail-ready redundancy – carry two, run one dry, swap, and keep moving.
  • Selector arrow – mark the “active” bottle to prevent a pile of half-used cylinders.
  • Left or right swing – reversible swing-arm to fit your layout.
  • Universal fit – Coleman disposable and Flame King refillable 1 lb bottles.
  • Mount anywhere – vertical panel, floor, platform systems, and pre-drilled for AAL Spare Tire Platforms and MOLLE bed panels.
  • Rattle-free in drawers/totes – even unbolted, it locks bottles from rolling.
  • Made in the USA – 5052 aluminum, laser-cut, corrosion-resistant, built in-house. 

When does a larger tank still make sense?

  • If you’re running a large griddle, patio heater, or campfire ring nightly, a 5 lb or 11 lb can simplify refills and cost per BTU. Many long-trip campers choose a 5 lb for economy but acknowledge the small 1 lb bottles are handier for day trips and portability.
  • Week-long trips with heavy cooking 5 lb tank Lower cost per fill, still compact
  • Group cooking, heaters, campfire rings 10–20 lb tank Long runtimes, fewer refills

Safety and handling reminders

Carry cylinders upright, secured, away from sharp objects and heat sources. Community guidance and propane safety pages echo this common-sense storage. 

If you prefer refillable 1 lb bottles, choose DOT-certified cylinders and follow manufacturer guidance. 

The bottom line

For many overlanders, dual 1 lb cylinders are the sweet spot — low weight, modular capacity, easy resupply, and no single point of failure. Pairing them with a purpose-built mount like the American Adventure Lab Dual 1LB Propane Tank Mount turns those “green bottles” from loose rattlers into a secure, professional system.
