7 Best External Propane Tank Mounts For Extended Boondocking

Extended boondocking requires a delicate balance between energy security and the physical limitations of a mobile dwelling. Running out of fuel in a remote location is more than an inconvenience; it turns a serene escape into a logistical crisis. Mastering your external propane storage ensures that your heat, cooking, and refrigeration systems stay running long after the local grid fades from memory.

Power Tank Propane Bracket: Best for Overlanding

When the terrain gets technical and the vibration of corrugated roads threatens to rattle gear loose, the Power Tank bracket stands as the premier choice. Constructed with industrial-grade materials, this mount is designed to withstand the violent jarring common in off-road recovery and high-clearance travel. It effectively eliminates the tank fatigue that often leads to stress fractures in lighter, cheaper alternatives.

The adjustable tension mechanism allows for a snug fit on various tank diameters, ensuring that the cylinder remains immobile regardless of the vehicle’s pitch or roll. For those piloting high-end overlanding rigs, this unit offers the structural integrity necessary to carry fuel externally without worry. If consistent, aggressive off-road performance is the primary goal, this is the gold standard for security.

Flame King Steel Tank Holder: Best Budget Option

Not every setup requires military-grade durability, and the Flame King Steel Tank Holder serves the needs of the practical camper perfectly. This holder is straightforward, functional, and achieves exactly what is promised: it keeps the tank securely fastened to your frame or trailer tongue without unnecessary bells and whistles. It is an ideal solution for those who stay primarily on maintained gravel roads or paved campsites.

While it lacks the heavy-duty reinforced plating of more expensive mounts, the steel construction provides sufficient rigidity for standard 11lb or 20lb cylinders. Installation is intuitive and fits most common RV tongue configurations. Choose this option if budget is a priority and your travel style avoids extreme vibration or high-speed washboard terrain.

MORryde Horizontal LP Mount: Best for Fifth Wheels

Fifth wheels often present unique mounting challenges due to limited space on the pin box or frame rails. The MORryde Horizontal LP Mount is engineered specifically to utilize horizontal space, keeping the propane system tucked away and out of the line of sight. This design is excellent for those looking to keep their exterior clean and aerodynamic while maintaining easy access for tank swaps.

The build quality matches the demands of large-scale towing, featuring powder-coated steel that resists the elements over years of exposure. Because the tank lays flat, the center of gravity remains lower, contributing to better towing dynamics. If a fifth-wheel configuration is the primary mode of travel, this mount is the most logical and space-efficient choice available.

Expedition Essentials Quick Mount: Best Quick-Release

Efficiency during propane swaps is a major advantage when cold weather necessitates frequent tank rotations. The Expedition Essentials Quick Mount features a high-speed locking mechanism that allows for near-instant detachment of the cylinder. It is designed for the traveler who needs to move quickly and values time-saving engineering over complex manual tightening processes.

This mount relies on a robust spring-loaded pin system that provides both security and accessibility. The materials are weather-resistant, ensuring the release mechanism does not seize up after exposure to mud, snow, or salt. If the ability to detach and swap fuel sources in seconds—perhaps in freezing conditions—is a requirement, this unit provides the most user-friendly experience.

AT Overland Propane Holder: Best Heavy-Duty Build

AT Overland creates equipment that is meant to outlast the vehicle it is attached to, and their propane holder is no exception. This mount is constructed from thick-gauge aluminum, offering superior corrosion resistance while remaining lighter than steel counterparts. It is designed to handle the harshest environments on the planet, making it the definitive choice for long-term, remote-area explorers.

The design utilizes a bomb-proof latching system that prevents any rattling or shifting, even under heavy loads. It is essentially a permanent, worry-free installation that removes the propane system from your list of mechanical concerns. For those who prioritize peace of mind on multi-month expeditions, the investment in this heavy-duty build is justified by its near-indestructible nature.

Manchester Universal Bracket: Most Versatile Fit

If you are dealing with a custom rig or a non-standard frame, the Manchester Universal Bracket offers the flexibility required to make unconventional mounting locations work. Its modular design allows it to be bolted to nearly any flat surface, from truck beds to trailer cross-members. It is the “Swiss Army knife” of propane mounts, designed to adapt to the constraints of your specific build.

Because it is highly adjustable, you can dial in the perfect height and orientation for your specific propane tank size. While it may require a bit more attention to detail during the initial installation phase, the end result is a highly customized fit. Opt for this bracket if your rig lacks standard mounting points or if you prefer a custom setup that isn’t beholden to proprietary sizing.

Stromberg Carlson Trailer Tray: Best for A-Frames

A-frame trailers often have limited tongue space, making standard upright mounts difficult to install without hitting the jack or the trailer body. The Stromberg Carlson Trailer Tray provides a dedicated, flat platform that mounts directly to the A-frame, creating a clean staging area for propane tanks and batteries. It expands the usable footprint of the tongue, keeping your heavy items organized and weight-distributed correctly.

The tray is pre-drilled to accept various tank mounting hardware, meaning it acts as a foundation rather than just a rack. It is a smart, forward-thinking addition for those who need to maximize every square inch of their front tongue area. If you find yourself struggling with a cluttered trailer tongue, this tray offers the best path to organization.

Choosing the Right Mount Location on Your Rig

Proper placement is just as critical as the hardware itself. The ideal location is well-ventilated, shielded from road debris, and accessible for easy maintenance. Avoid mounting propane tanks directly behind the vehicle’s tires, where rocks and road spray can damage valves or regulator hoses.

Always prioritize weight distribution. Placing heavy tanks on the extreme rear or the far front of a trailer can drastically affect tongue weight and towing stability. A balanced rig handles better and puts less stress on your suspension components during long-term travel.

Mounting Your Tank: Safety and Best Practices

Safety is not an area for shortcuts. Ensure that every bolt, nut, and washer used to secure the mount is grade 5 or higher and secured with nylon-insert lock nuts to prevent vibration-induced loosening. Inspect these connections every few thousand miles; a loose mount is a hazard that can lead to gas leaks or structural damage to your trailer frame.

Orientation matters just as much as physical security. Always ensure the tank is mounted in a position that allows the pressure relief valve to function correctly and remain unobstructed. A tank mounted sideways or upside down poses a severe risk, as it may release liquid propane rather than vapor in an overpressure event.

Propane System Checks for Extended Trips

Before embarking on an extended boondocking journey, conduct a comprehensive pressure check on your entire gas system. Use a soapy water solution to identify even the smallest pinhole leaks at every connection point, particularly where the tank pigtail meets the regulator. Do not assume that because a system worked last season that it is airtight today.

Keep a spare regulator and extra pigtail hoses on hand at all times. These parts are often the first to fail under the stress of constant temperature changes and vibrations. Maintaining a proactive approach to your propane system ensures that your living space remains safe and comfortable, no matter how far you are from the nearest supply store.

Investing in high-quality, secure propane mounting is a fundamental step in building a reliable and safe boondocking setup. By selecting hardware that matches your specific terrain and travel frequency, you minimize the risk of mechanical failure and maximize your off-grid independence. Choose the mount that aligns with your lifestyle, and you will spend far less time worrying about your fuel supply and much more time enjoying the landscape.
