Our Reviews: Pros, Cons & More

Ready? Let’s get into the nitty gritty details for all of our top picks.

Best Battery Monitor

Baylite LCD Display Current Voltage Meter

If you need to keep an eye on your battery levels, this is the best RV monitor panel for the job. It has an LCD display that gives you all the readouts you’ll want, including battery, fridge, and more, while simultaneously telling you what percentage of battery each of your devices uses.

The LCD display has a nice blue, glowing light, but—even better—this monitor saves your energy data even when it’s turned off until you reset it. Best of all, the monitor measures within a one percent margin of accuracy of energy levels, and it has an overload alarm.

However, I’m not fond of how you have to look at the display screen directly to be able to read it. The light isn’t very bright, and the device as a whole is a bit cumbersome when mounting.

Best for Large RVs

DROK AC 80-300V 100A LCD Display

One feature I like about the DROK monitor panel is that it displays not only active power but also the electric quantity, voltage, and ampere values. It also remembers data even when it loses power and will keep your readings until you reset it. Plus, it works in a wide range of temperatures and measures accuracy within one percent of actual levels.

Unfortunately, this isn’t the sturdiest of all the monitors on this list, and you may damage it while you’re installing it. While the LCD display might be great and bright enough to easily read, the smaller pieces are very delicate, so you’ll need to be careful when you assemble and install it.

Pros:

• Accurate readings
• Has a current transformer
• Easy to read
• Holds onto data even without power
• Straightforward installation

Cons:

• Mounting can be a challenge
• Smaller pieces may break off if not carefully handled during assembly

Best Smart Display

SIMARINE Pico Blue Package

I like SIMARINE for a lot of reasons, but especially because of its smart tech. It’s perfect for monitoring the health of your battery, is easy to use, and gives accurate readings. Even better, you can customize it and add modules onto it, but it also allows you to monitor your data (including lights, refrigerator, solar panel, and other instruments) from your phone via an app.

If you want free help with this unit, you’ll have to use email support, and getting a timely response is hit or miss. It doesn’t have Bluetooth compatibility, which is odd for smart tech. Further, you can’t turn the screen off completely, only lower the brightness, and the barometer graph will only display up to three days of data at most.

Pros:

• The glass is gorilla glass, so it’s sturdy
• Straightforward installation
• Simply to navigate
• Great smart tech
• Easy to use

Cons:

• You may have to pay for phone support
• No Bluetooth
• Cannot turn off the screen
• The barometer graph only displays three days at most

Best Tank Monitor

SeeLevel II Tank Monitor

When there is a need for RV tank monitors, this is always my go-to choice. It works on a variety of different RVs and provides accurate tank level readings. Best of all, it’s easy to read, and I can customize it to the specifications that I need. It’s pretty straightforward to assemble, too, but it works best if your RV has three holding tanks: fresh, black, and gray.

One of the drawbacks is that it won’t work on a metal surface, so you need to be sure you have plastic or poly. It sometimes has trouble syncing with certain vehicles, so it’s a good idea to contact the manufacturer to ensure yours will work. And, while assembly may be decently easy, installation is occasionally a challenge.

Pros:

• Fits a wide variety of different vehicles
• Simple, easy-to-read display
• Holding tank sensors available in three lengths
• Provides accurate readings

Cons:

• Doesn’t work on metal surfaces
• I may have trouble syncing with some vehicles
• Confusing installation

Best Small Monitor

KIB M21VW Micro

If you’ll forgive the cliche, the KIB Micro is an oldie but a goodie. It does what you need it to do, including manual control of the lights and water pump from the monitor itself. It monitors gray, black, and fresh water tanks, as well as your battery. This monitor tells you when it’s full, at two-thirds, one-third, and empty. There’s a reason why it’s called Micro as it fits just about anywhere you want to put it.

However, it doesn’t show a percentage because it’s simply a red light display without any digital elements. Though it does a basic job, its limited design means you may not get accurate readings. Plus, the plastic casing feels lightweight and cheap, which is okay considering its price.

Pros:

• Fits anywhere in the RV
• One of the easiest to use
• Can turn the water pump and led lights on and off with it
• Fantastic price

Cons:

• Overly simply display
• The instructions may not be clear
• The plastic casing feels cheap
• Readings not as accurate as others

Buying a New RV Monitor Panel: What to Look For

Don’t know where to start when you’re buying a monitor panel for your RV? These factors are important to consider before you buy a new monitor panel.

Mechanical Control Features

Many of the older monitor panels are pretty simple. They monitor the basics, and they may or may not have a control switch for the water pump. Newer models often come with additional control features.

In fact, some allow you to turn the lights on or off while some offer control over any slide room mechanisms or other mechanical features your RV might have. These might include your water heater, furnace, and more.

I know that when I shop for a monitor panel, I make sure it handles more than the basics. Specifically, I look for a monitor panel that will even monitor the temperature of my fridge to ensure I don’t have to deal with food spoilage.

Remember that means your fridge needs to be at 40 degrees at all times. Otherwise, you may end up eating something off and get a foodborne illness. The importance of a monitor panel that gives readouts for the fridge and freezer cannot be overstated.

Levels Display

As I’ve discussed, each model has different displays. At the very least, I’ll want the fresh water tank, black water main, gray water main, any secondary mains, and battery levels all covered by any monitor panel I consider.

I might consider it a bonus to have something that shows me the fuel level for my generator. However, one thing I won’t budge on is a digital display. I find them to be more accurate and allow me a better ability to monitor where things actually stand, rather than a rough estimation.

Having precise readings is a priority. Not only is there the risk of having a tank empty out before you planned for it to, but they may overflow. Overflow is dangerous not only because of the risk of water damage, but because dampness can lead to black mold growth. As you may already know, mold is dangerous because it can lead to respiratory illness, asthma-like symptoms, coughs, and throat and lung issues.

Temperature Monitoring

Other than the fridge, it’s good to monitor the overall temperature of your RV too. This is not only a convenient way to ensure you’re never uncomfortable, but it may save you a bit of money, too.

If you’re going out for the day, you can program it from one place to make sure you don’t waste energy on heating or AC while you’re not around to enjoy it unless you have pets.

Dogs, cats, and other pets all respond differently to temperature than humans do, especially heat. When it’s hot out, even leaving a fan on won’t be enough to keep your pet cool inside. If you leave for the day, it’s a good idea to program the thermostat to ensure your pet doesn’t overheat while you’re gone.

Many newer models will have a feature that lets you know if there is a temperature spike or sudden drop. This way, you’ll get an alert, which means you can head back and check on Fido to make sure everything is okay.

The Level of Communication

Speaking of text or email alerts, I typically want something that will text or alert me when my tank or energy levels are low, or if there is an emergency.

It’s particularly useful on days when I know I’m going to spend most of my time out of the RV. This way, I don’t have that nagging fear hanging over me that something might be going wrong at home, and I can enjoy my time outside.

And that’s about it for monitoring panels. If you’re having trouble with yours, be sure to read Brian’s guide on RV monitor panel troubleshooting.
