What is an RV Monitor Panel?

An RV monitor panel is simply the information center of your entire RV. This product is usually located in a place where it is easily accessible and readable such as the hallway or the kitchen. These monitors have old models as well as new ones.

The old models tend to provide information on the freshwater tank, holding tank, the battery power levels, and the LP power as well. On the other hand, the newer models allow you even to adjust the sensitivity of the monitor panel and have many more options.

How to Choose a Monitor Panel For Your RV

When investing in the best RV monitor panel, you will have to look for some specific features. These features help in determining the worth of your item.

Receiving Alerts and Texts

Many monitors nowadays make use of text messages and alerts as soon as something gets out of hand. This feature is quite essential, especially if you have a job all day long. These texts keep your pets and other things at home safe. These can easily be customized for many different settings, including humidity, temperature, and battery voltage. So, make sure to get a monitor that allows you to customize these messages and also alerts you right away.

Food Safety

When in an RV, it is very important that you store food. Since the place is compact, you must have food prepared beforehand but refrigerating food in an RV is extremely challenging. Many RVs make use of electric and propane fridges; however, keeping food at a safe temperature even in these fridges can be a tough job in hot weather conditions.

With a good RV monitor control, you will know beforehand if your fridge is cold or hot. If the freezer temperature drops or remains at a temperature for too long, this control can send you an alert, so you can take care of the food right away.

Interior Temperature

Another feature to look for is monitoring the interior temperature and setting it yourself. If you live with pets that you have to leave behind in your RV, then you must buy a unit that keeps track of the interior temperature. This way, you can relax knowing they are safe from danger during the vicious heat or extreme cold.

If the RV interior temperature rises above or below a threshold temperature you have set on the monitor; you will get a text or message warning you. This way, you can rush back home and make things right.

What Recent Buyers Report

According to most customers, the product performed as they expected it to. People reported that it gave accurate results every time they used it. Plus, its reset feature allowed them to observe readings, even when the power was shut off.

After acknowledging all the reviews, the device seems to be worth buying.

Why it Stands Out to Us

All the observations displayed on the LCD don't disappear unless the user deliberately formats it. This means he doesn't miss out on the readings, even during the unavailability of power.

Bottom Line

Types of RV Monitor Panels

The advancement of technology has greatly contributed to the modernization of monitor panels. To date, there have been three types of monitor panels that are different from each other on account of various factors like viewing angles, color contrasts, response rates, etc.

DROK AC 80-300V 100A Voltage Current Color LCD Display Panel

It's necessary to select the right monitor for getting the desired results. And this is possible only if you know each type of monitor panel. For your convenience, here are details of each type. 

Twisted Nematic Panels

This is the earliest panel engineered for monitors. It features exceptionally high response and refresh rates. Moreover, it offers a high-resolution and well-contrasted output and comes at an affordable price.

But it lacks optimum viewing angles. The panel displays a somewhat color-perverted picture on viewing it from off angles.

Vertical Alignment Panel

Its viewing angles are better than the TN panel. Also, the color contrasts, brightness level, and image clarity are worth-watching. But this type of panel fails to keep up with fast response rates.

In-Plane Switching (IPS) Panel

This is an advanced form of other panel types. It excels at pixel transition, color depth, image resolution, and crisp pictures at wide viewing angles.

Whether due to the versatility or ever-increasing market demand, you will always find IPS monitors on the list of expensive products.

How to Read an RV Monitor Panel

RV monitor panels come in various designs, but all of them are simple and easy to use. Staple measuring units are used for representing readings. Moreover, the markings are legible so the user can see the readings with ease.

If you are new to RV monitor panels and want to understand what the figures displayed on the meter screen mean, this section will be quite helpful to you.

  1. On the panel, you will find the fields of measurement mentioned in a straight alignment as gray water, black water, freshwater, and battery.

  2. Gray water represents water coming through showers and sinks; black water represents toilet water, whereas freshwater means drinking water.

  3. Next to all this, there are options printed as C, G, F, and L denoting charging, good, fair, and low. These symbols indicate the level or condition of the water present in the tank.

  4. An LED light is situated for each marking right beside it. The water level is indicated by up to what rank LEDs are illuminated. For instance, if LEDs starting from the lowest point are illuminated up to the fair, it means the tank is currently housing only 1/3 water of the total capacity.

For more details, be sure to refer to the video below for a full overview of what was just described.

How to Clean an RV Monitor Panel

If your monitor panel shows issues like all LEDs illuminated and improper readings, then it's time to troubleshoot the device. The reason behind false readings is the gunk or debris accumulated around the meter's sensors or on the walls of the tank.

This debris can be removed, and the device can be brought back to its original condition by following a few steps.

  1. First, flush multiple buckets of water in the toilet. The high-pressured flow of water may help drain out the dirt.

  2. If the problem persists, fill the tank to the fullest and add some cleaning solution to it. But make sure the water doesn't come out of the tank.

  3. Leave the water in the tank for a few hours. In the meantime, debris melts or dissolves in the water.

  4. Empty the tank and check the device's performance.

  5. If the problem is still there, you can go for a more effective method.

  6. This time, you have to fill the tank with extremely hot water and let it sit for a while. You can also use cleaning sticks to scrape off the stubborn dirt.

  7. Then, drain the water and check the results.

We hope these steps will help you in getting rid of the problem. For further assistance, you can have a look at the video below. 


RV monitor panels are an ideal investment for your RV. They are useful and very efficient in their functions. However, finding these on your own can be a tough task. To make this easy for you, we have compiled a list of the best RV monitor panels on the market, along with their pros and cons. Pick one of these to maintain your RV easily and efficiently.
