The Best RV Propane Tank Gauges for 2025

You’re out in the middle of nowhere, campfire crackling, stars overhead, and you’re about to whip up some s’mores when—oops—your propane tank runs dry. No hot water, no stove, no heater. Been there? Yeah, me too. That’s why finding a reliable propane tank gauge is a game-changer for any RV adventure. These little gadgets keep you in the know about your propane levels, so you’re never caught off guard. Today, I’m diving into the best RV propane tank gauges for 2025, comparing top picks, sharing what makes them shine, and helping you choose the right one for your rig. Let’s get started!

Why You Need an RV Propane Tank Gauge

If you’ve ever tried the old “shake the tank” method to guess how much propane is left, you know it’s about as reliable as a weather forecast from a groundhog. A good propane tank gauge takes the guesswork out of the equation. It tells you exactly (or close enough) how much fuel you’ve got, so you can plan refills before you’re left high and dry. Plus, many modern gauges come with safety features like leak detection, which is a big deal when you’re dealing with flammable gas. Whether you’re boondocking in the desert or parked at a cozy campground, knowing your propane status means one less thing to stress about.

But not all gauges are created equal. Some measure pressure, others use ultrasonic tech, and some even connect to your phone. Each type has its perks and quirks, so let’s break down the top options and see which one fits your RV lifestyle.

Top RV Propane Tank Gauges: A Detailed Comparison

After scouring reviews, forums, and product specs, I’ve rounded up five of the best RV propane tank gauges available in 2025. These picks stand out for their accuracy, ease of use, and camper-friendly features. Below, I’ll dive into what makes each one tick, but first, here’s a quick comparison table to give you the lay of the land.

SHINESTAR Propane Tank Gauge: The Budget-Friendly All-Rounder

If you’re looking for a no-fuss, wallet-friendly option, the SHINESTAR Propane Tank Gauge is hard to beat. This pressure gauge screws between your tank and regulator, giving you a color-coded dial (green for full, yellow for low, red for “get to a refill station ASAP”). It’s super easy to install—no tools required—and fits tanks from 5 to 40 pounds, making it versatile for most RV setups.

What I love about the SHINESTAR is its simplicity. You don’t need to be a tech wizard to use it, and it comes with a leak detector to keep things safe. Users on SmartRVing praise its airtight brass construction and clear dial, though some note it’s less accurate in extreme cold. For under $20, it’s a solid pick for casual campers who want peace of mind without breaking the bank.

Pros: Abordable, easy to read, safety features.
Cons: Pressure-based, so not pinpoint accurate in all conditions.

Mopeka Pro Check Sensor: The Tech Lover’s Dream

For those who like their RV gear with a side of high-tech, the Mopeka Pro Check Sensor is a standout. This ultrasonic gauge sticks to the bottom of your tank with a magnet and pairs with a Bluetooth app to show real-time propane levels on your phone. No more crawling under the RV to check a dial! It’s compatible with 20- to 100-pound tanks and works with systems like Victron for integrated RV monitoring.

Reddit users on r/RVLiving rave about its accuracy and ease of use, especially for boondockers who need precise readings. The downside? It’s pricier, and you’ll need to swap out the coin battery every year or so. Also, the magnet can slip if your tank’s bottom is rusty, so a dab of dielectric grease helps keep it in place.

Pros: Highly accurate, surveillance à distance, durable.
Cons: Higher cost, requires smartphone and occasional battery changes.

Camco Propane Gauge/Leak Detector: The Safety-First Choice

The Camco Propane Gauge is a crowd favorite for its blend of reliability and safety features. Like the SHINESTAR, it’s a pressure gauge with a color-coded dial, but it stands out with temperature-adjusted readings that stay accurate even in chilly weather. It also has excess flow protection, which cuts off gas in case of a major leak—perfect for peace of mind on long trips.

RV Chicks highlights its compatibility with post-1995 DOT cylinders and easy hand-tight installation. Some users report it’s a bit bulky, which can be an issue in tight RV propane compartments, but its sturdy brass build makes it a long-lasting choice.

Pros: Temperature compensation, safety features, trusted brand.
Cons: Bulkier than some, pressure-based limitations.

Truma LevelCheck: The Portable Powerhouse

If you’re a frequent traveler who needs a gauge that works across multiple tanks (RV, grill, or otherwise), the Truma LevelCheck is your go-to. This ultrasonic device is handheld, using LED lights to indicate propane levels when pressed against the tank. It’s lightweight, works in temps from 5°F to 104°F, and doesn’t require permanent installation.

MeasureDay calls it the most versatile gauge out there, ideal for RVers who swap tanks often or use propane for more than just their rig. The catch? It’s expensive, and you need to actively check the tank rather than getting passive readings. Still, its accuracy and portability make it a top pick for adventurers.

Pros: Portable, works in extreme temps, highly accurate.
Cons: Pricey, manual operation.

GASLAND 2-Way Splitter Gauge: The Multi-Tasker

Got a generator and a grill running off the same tank? The GASLAND 2-Way Splitter Gauge lets you power two appliances while monitoring propane levels. This pressure gauge has a color-coded dial and a built-in leak detector, all wrapped in a durable brass body. It’s a great fit for RVers who need flexibility without sacrificing safety.

BBQ Hero praises its ability to handle dual setups, though some users note the dial can be hard to read in low light. It’s a bit more expensive than basic pressure gauges, but the splitter feature makes it worth it for multi-appliance campers.

Pros: Dual-appliance support, sturdy build, safety features.
Cons: Dial visibility, slightly higher cost.

How to Choose the Right Gauge for Your RV

With so many options, picking the best gauge comes down to your specific needs. Here are a few things to consider:

• Tank Size and Setup: Make sure the gauge fits your tank (most RVs use 20- or 30-pound tanks) and connection type (usually Type 1/QCC1). Check your RV’s manual or existing setup to confirm.
• Accuracy Needs: Pressure gauges are cheaper but less precise, especially in extreme temperatures. Ultrasonic gauges like Mopeka or Truma offer better accuracy but cost more.
• Tech Comfort: If you love apps and remote monitoring, go for a Bluetooth-enabled gauge like Mopeka. If you prefer analog simplicity, stick with SHINESTAR or Camco.
• Safety Features: Look for leak detectors or excess flow protection, especially if you’re camping in remote areas.
• Budget: You can get a reliable pressure gauge for under $30, but high-tech options run $60-$120.

The Pros and Cons of Different Gauge Types

Let’s take a quick look at the main types of propane gauges and what they mean for you as an RVer.

• Pressure Gauges: These measure gas pressure, not liquid volume, so they’re less accurate but super easy to install. They’re great for casual campers but can be thrown off by temperature changes. Examples: SHINESTAR, Camco, GASLAND.
• Ultrasonic Gauges: These use sound waves to detect liquid levels, offering top-notch accuracy. They’re pricier and may require batteries or an app, but they’re perfect for serious RVers. Examples: Mopeka, Truma.
• Weight-Based Scales: These measure propane by weighing the tank. They’re accurate but a pain to use on secured RV tanks, so they’re less common for camping. Example: Flame King Smart Scale.
• Magnetic/Temperature Gauges: These stick to the tank and show levels based on temperature differences. They only work when gas is flowing, making them less practical for RV use.

For most RVers, pressure or ultrasonic gauges strike the best balance of cost, ease, and reliability. If you’re on a budget, a pressure gauge gets the job done. If you want precision, ultrasonic is the way to go.

Real-World Implications: Why Your Gauge Matters

A propane gauge isn’t just about convenience—it can make or break your trip. Running out of propane in the middle of a chilly night means no heat, no hot meals, and a grumpy crew. On the flip side, overfilling a tank or missing a leak can be dangerous. A good gauge helps you avoid these headaches by giving you clear, timely info.

For example, let’s say you’re boondocking for a week. A pressure gauge like the SHINESTAR might tell you when you’re low, but it won’t give you an exact percentage. If you’re running a fridge, furnace, and stove, you could misjudge and run out early. A Mopeka sensor, with its app-based precision, lets you track usage down to the percentage, so you can ration or refill in time. Safety-wise, gauges with leak detectors (like Camco or GASLAND) can alert you to issues before they become hazardous, especially in tight RV compartments.

Tips for Using Your Propane Gauge Like a Pro

Once you’ve got your gauge, here are a few tricks to get the most out of it:

• Install Correctly: For pressure gauges, hand-tighten between the tank and regulator, and use thread seal tape for a snug fit. For ultrasonic sensors, ensure the tank bottom is clean and the sensor is centered.
• Check Regularly: Make it a habit to glance at your gauge before and during trips. Apps like Mopeka’s make this a breeze.
• Calibrate for Accuracy: Some gauges, like Mopeka, let you calibrate for tank size in the app. Do this for the best results.
• Store Safely: Remove ultrasonic sensors when traveling to avoid losing them, and cover pressure gauges to protect from dust and moisture.
• Pair with a Backup Plan: Carry a spare tank or know where the nearest refill station is, just in case.
