7 Best RV Propane Regulators for Safe Camping Nomads Swear By

You wake up to a cold rig, the furnace silent, and realize you’ve run out of propane in the middle of the night—again. That tiny, often-ignored device mounted between your propane tanks is the key to preventing this, and more importantly, to ensuring your entire gas system operates safely. Your RV’s propane regulator is the unsung hero of your rig’s comfort systems, and choosing the right one is one of the most critical safety decisions you’ll make.

Understanding RV Propane Regulator Essentials

Your propane regulator has one job: to tame the high-pressure gas coming out of your tanks. It steps that pressure down to a low, consistent level that your appliances—furnace, water heater, stove—are designed to use safely. Without it, you’d have an uncontrolled, dangerous flow of gas.

Most modern RVs use a two-stage regulator. The first stage makes a big pressure drop, and the second stage fine-tunes it to a precise, steady output. This two-step process ensures your flame doesn’t sputter when another appliance kicks on, providing a much safer and more consistent experience than older single-stage models.

If you have two propane tanks, you’ll want an automatic changeover regulator. This brilliant device automatically switches to the full tank when the primary one runs empty, so your heat doesn’t die at 3 AM. A small indicator flips from green to red, letting you know it’s time to go get the empty tank refilled, all without any interruption in service. When you shop, you’ll need to match the regulator’s BTU rating to your rig’s total demand; just add up the BTU ratings of all your propane appliances to find your minimum.

Camco 59005: The Automatic Changeover Standard

If you’ve looked at the propane setup on a dozen different travel trailers, you’ve likely seen the Camco 59005 or a clone of it. This is the industry workhorse—the default choice for countless manufacturers and a reliable replacement for most standard RVs. It does exactly what it’s supposed to do without any fuss.

Its dual-tank, auto-changeover functionality is the main draw. You set the lever to point at your primary tank, and when it’s empty, the regulator seamlessly draws from the second tank while the indicator turns red. This simple visual cue is your signal to refill the empty cylinder. With a 210,000 BTU/hr capacity, it has more than enough power for the typical furnace, water heater, fridge, and cooktop running together.

The Camco is not the fanciest or most robust unit on the market, but it is affordable, widely available, and easy to install. For the vast majority of weekend campers and seasonal travelers, it’s a perfectly adequate solution that balances cost and performance. It’s the definition of a known quantity.

Marshall Excelsior MEGR-253: High-Flow Choice

When you live in your rig full-time or have a larger coach with high-demand appliances, the standard regulators can sometimes struggle. Running the furnace, the tankless water heater, and the oven all at once can cause a pressure drop, leading to poor appliance performance. This is where the Marshall Excelsior MEGR-253 shines.

This is a high-flow, or high-capacity, regulator. With a rating often exceeding 400,000 BTU/hr, it can handle a massive load without breaking a sweat, ensuring every appliance gets the consistent pressure it needs. It’s an upgrade that solves those mysterious performance issues that often get blamed on the appliances themselves.

Marshall Excelsior is also known for its build quality. These regulators are heavier, built with better materials, and designed to withstand the vibrations and temperature swings of life on the road. If you’re tired of replacing cheaper regulators every few years and want a "buy it once" solution for a demanding setup, this is the one to get.

Flame King KT12ACR6: A Reliable Two-Stage Unit

The Flame King KT12ACR6 is a direct and formidable competitor to the Camco standard. It offers the same essential two-stage, automatic changeover functionality but is often favored by RVers who prioritize a reputation for consistent manufacturing and quality control. It’s a solid, dependable choice that many nomads swear by after having other brands fail.

Functionally, it operates just as you’d expect. You connect your two tanks, select your primary, and it handles the rest. The green/red indicator is clear and easy to read, and the unit comes with the necessary mounting bracket for a straightforward installation. Its BTU capacity is more than sufficient for most RVs, making it a versatile replacement part.

Choosing between the Flame King and the Camco often comes down to user experience and brand loyalty. Many experienced RV technicians and full-timers lean toward Flame King, citing better long-term reliability and fewer premature failures. If you’re looking for a slight step up in perceived quality without moving to a high-cost, high-flow model, Flame King is an excellent middle ground.

Fairview GR-9984: Compact and Durable Design

Sometimes, the challenge isn’t performance but space. RV propane compartments can be incredibly tight, and fitting a bulky regulator and its associated pigtail hoses can be a frustrating puzzle. The Fairview GR-9984 addresses this head-on with a notably compact and well-engineered design.

Beyond its smaller footprint, the Fairview’s main selling point is its construction. Made with a solid zinc body and high-quality internal components, it’s built for longevity. This regulator feels substantial in your hand, inspiring confidence that it can handle the elements, from road salt in the winter to humid coastal air in the summer. It’s a piece of hardware designed for industrial use, adapted perfectly for the rigors of RVing.

This is the regulator for the RVer who appreciates robust engineering and needs to optimize every inch of space. It provides the same reliable auto-changeover performance as its competitors but in a package that’s both tougher and tidier.

Mr. Heater F273763: For Portable Heater Setups

Not every regulator is for your main RV system. Many nomads rely on portable propane heaters, like the iconic Mr. Heater Buddy, for supplemental heat or outdoor use. The endless cycle of buying and discarding 1lb green disposable canisters is both expensive and wasteful.

The Mr. Heater F273763 hose and regulator assembly is the solution. This simple device allows you to connect your portable appliance directly to a standard 20lb or 30lb propane tank. The hose is typically 10-12 feet long, giving you flexibility in where you place your heater or camp stove relative to the large tank.

This is a single-stage regulator, which is all that’s needed for this application. It steps down the pressure to what the appliance expects, providing hours or even days of runtime from a single large tank. For anyone who uses a portable propane appliance regularly, this accessory is not a luxury; it’s an essential piece of gear for convenience and cost savings.

Gasland Two-Stage Auto Changeover Regulator

For the budget-conscious RVer, finding parts that are both affordable and reliable is the name of the game. The Gasland Two-Stage Auto Changeover Regulator fits this niche perfectly. It offers all the core features of the big-name brands—two-stage regulation, automatic switching, and a visual indicator—at a price point that’s hard to beat.

This is a fantastic option if your old regulator suddenly fails on the road and you need a quick, cost-effective replacement to get your systems back online. Many of these kits also come complete with two new pigtail hoses, adding even more value and saving you a separate purchase.

While some might question the long-term durability compared to a premium brand like Marshall Excelsior, thousands of users have found the Gasland to be a perfectly capable performer. For many, it provides years of trouble-free service, proving that you don’t always have to spend top dollar to get a safe and functional component for your rig.

MB Sturgis 25-350: A Quick-Connect Solution

The MB Sturgis 25-350 is for the RVer who loves their outdoor kitchen. One of the biggest hassles of using a propane grill, griddle, or fire pit is dealing with a separate tank. This regulator elegantly solves that problem by integrating a female quick-connect port directly into the regulator body.

This port provides a regulated, low-pressure supply of propane, allowing you to plug your outdoor appliances directly into your RV’s main tanks. No more carrying an extra 20lb tank just for the grill. You simply run a quick-connect hose from the regulator to your appliance and you’re ready to cook.

This isn’t just about convenience; it’s about creating a more integrated and streamlined camping experience. By building this functionality right into the heart of the propane system, MB Sturgis has created a must-have upgrade for anyone who spends more time cooking outside than inside. It’s a smart design that simplifies your setup and reduces the amount of gear you have to haul.

Ultimately, the best propane regulator is the one that safely meets the demands of your specific setup. Whether you need a high-flow model for a luxury fifth wheel, a compact unit for a tight space, or a quick-connect for your outdoor grill, the right choice ensures your appliances run smoothly and reliably. Treat your regulator as the critical safety device it is—inspect it seasonally, perform leak checks regularly, and replace it at the first sign of wear.
