You plan every trip carefully, but water and waste don't always follow your schedule. With percentage-based readings, alarms, and Bluetooth smartphone access, this monitor ensures you'll always know when its time to fill, dump, or refuel.
Traveling in your RV should feel freeing, not stressful. Nothing disrupts a trip faster than running out of fresh water or discovering a tank is full at the wrong time. The SeeLeveL system removes the guesswork. Instead of vague 1/3 or 2/3 full readings, you see exact percentages for each tank. Custom alarms let you know the moment attention is needed, so you stay in control before small problems turn into big ones.
Convenience matters on the road. Bluetooth compatibility lets you check tank levels right from your phone, and a built-in switch gives you one-touch control of your water pump. Add in battery voltage monitoring and you have a complete picture of your RV's resources from a single display.
The system supports multiple fresh, gray, black, and LPG tanks, with the option to repurpose the LPG input for a third gray tank if needed. Installation is straightforward using SeeLeveL Senders (sold separately) mounted outside your tanks, and accuracy is dependable from day one.
From bright desert sun to daily vibration, this monitor is designed for RV life. The LED brightness adjusts for visibility anywhere, and you can add multiple monitors to check levels inside or from the service bay. If you're dry camping far from hookups or cruising cross-country, this system gives you total control over your resources.

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this SeeLevel RV holding tank monitor for seven tanks with the water pump switch and Bluetooth capability. Now, this is gonna allow advanced tank monitoring for your advanced RV. It is compatible with the multiplex RVC systems so that you can get improved readings at your primary control panel. This will hardwire to SeeLevel sensors that are mounted on the outside of your tanks. Those sensors we do sell separate on our website.
This monitor's gonna display the levels of your RVs fresh, gray, and black tanks. At just the push of a button right here where the display is, it'll show zero to 100%. Now this can monitor two fresh, two black, and three gray water tank levels. It will also, the button here that says battery, it'll detect battery voltage and as we mentioned also, activates the water pump with the integrated switch. And over here you can see the LPG button.
This display can use an existing LPG electrical center to show the LPG level. This display does have Bluetooth wireless technology, which allows you to check your tank levels, your battery voltage, and LPG tank levels on any compatible smartphone or tablet device with a free downloadable app available on Google Play or iOS app stores. As we mentioned, it's compatible with RVC multiplex systems to display the tank levels on your center console. This will check status and signal strength of the sensors using a diagnostic mode helps improve accuracy during your install. And it will alert you of any errors or calibration issues with various display codes.
And those codes will be explained with suggested solutions in your user manual. Now, this is designed to work with multiple monitors so you can check tank status from the service bay and inside your RV. This does install very easily. You'll just cut a hole for the recessed mount monitor and then screw it into place. Now the hardware's not included, but if you notice, it does include the pigtail that's needed for installation, plugs in the back there, and existing wiring from your old tank monitor system can be used to ease the install.
Again, application is for seven holding tank setups with multiplex systems. Operating temperature is 32 degrees Fahrenheit up to 140 degrees Fahrenheit, and operating voltage range 11 volts to 16 volts. Last thing is just the measurement of this monitor. Width of it is four inches wide. The height bottom to the top two and thirteen sixteenth inches tall, and the total depth from the front to the very back here is three quarters of an inch. But that's gonna do it for a look at the SeeLevel RV holding tank monitor for seven tanks with a water pump switch and Bluetooth capabilities.

Great customer service fair price and follow thru…

As always, great job!
Found a hard to find part for my Airstream trailer at a great price! Plus, very timely free shipping! Can’t beat that!!
I used one of these in another trailer and love it. That’s why I bought one for the trailer I am currently rebuilding. I had a sender problem with one tank and their customer service was wonderful helping me find a solution to the specific problem that existed.
replaced the WGO OEM panel with this one as it had all the options that I needed and fit nicely into the same area... as with the sensors, it was an easy single-wire install (for the sensors) and gives a much more accurate indication of the tank status'... would highly recommend this product!
Combined with the sensors perhaps the best upgrade to my trailer.
Monitor works great. Fast shipping.
Part repaired our tank sensor for our gray tank on our DRV.
The SeeLevel system has worked flawlessly. It is a vast improvement over the tank monitoring system that came with our Airstream.
not needed so I returned it, but not the fault of etrailer.
This was the item I needed. Informative videos, Fair price, fast delivery, fixed the gray tank reading issue. Thank you
Got it quickly and came as advertised and is working like it should very happy with it and etrailer was very easy to order it from. Will definitely buy from etrailer again
This was a replacement panel for one of the same model that failed.. the new panel went into place and works well..
Easy installation and they work great
eTrailer is my go to for trailer parts. Large inventory and they carry specialized replacement parts. Competiveky priced and fast shipping.
Excellent service from e trailer unfortunately it is the wrong item to replace the one that is no longer operating.
After doing some you-tube research and chatting with the SeeLevel tech team, I felt safe that my unresponsive tank level reading was caused by a faulty tank sensor. This fixed the problem.
I am surprised, and delighted, that eTrailer has expanded their inventory to include RV parts. As always, great selection, helpful videos, fair pricing, and quick shipping all make for a swell experience. Thank you!
I bought this SeeLeveL display to replace one which had stopped lighting up some of the LED segments. I just matched the display functions of the old one when I made my order using the product images on the etrailer website. The new one was a direct drop-in replacement. The connector pins on the new one were bent and had to be straightened which I did by hand with a key. Once plugged in and tested all the displays segments worked based on the tank levels at the time and were brighter than the old display. The display arrived within a few days of placing the order as predicted. I like the etrailer website and the service they provide.
Great product and great service! Thank s!
Install was the challenge, I was replacing the stock non Bluetooth version that came on our 2025 Airstream. The mounting pattern was identical so that was great. There is no documentation included and the wire colors from the original one do not match the new one. I had to find schematics for both units on the internet and figure out old function/color to new function/color. In the end it worked fine.
I'm looking forward to installing this in the rig to add blue tooth capability to the SeaLevel system. This will make it convenient to be outside of the rig while draining the tanks or adding fresh water.
This unit is not "Plug & Play. I am replacing the original (1yr old) SeeLevel II with the 7090-BTP7 and it would not work. Calling Garnet Tech support, the supplied pigtails with plug must be used. Wires from the RV need to be cross referenced.
I installed the system about a week ago. So far it is working beautifully! I have a 2022 Renegade Verona LE and the original Firefly system was never reliable. I installed the panel in my wet bay and use the Bluetooth feature to check the levels when I'm in the rig.

Sorry about the lack of instructions, Todd. We do have them on the website, so I'm a little surprised they weren't included with the product. I'll have our stock checked to see if maybe they got left out on this batch or something.
