My motorhome came with the vent hood over the stove equipped with a tank monitoring system and water pump switch. I hated this system from day one, and to top it off the vent was never vented out side so it was useless as well. So a aftermarket tank monitoring systems has been on my hit list for my motorhome.

There are 3 systems out there, but I really focused in on SeeLevel because of the ease of installation. I met with them at the RVIA show last December and after getting a crash course on the product and a explanation on the installation, I decided SeeLevel was the monitoring system for me.

I finally got a chance to install a system last weekend and I am very pleased with every aspect of the product and the installation. I will be very honest, I was worried about the installation with regards to the wiring. It just seemed like it was going to be a real pain in the neck. Would my motorhomes wiring match up with what the SeeLevel system would require and if not would I have to pull wires from my tanks and ????

Well all of that worrying was for not. It truly was a easy install.



Above I show a photo of what the overhead stove vent looked like before replacement. Ugly! It was held in with 4 screws, so it was easy to remove. Next I needed to determine which wires went to what. On the old monitor board it was labeled which wire went to which tank, along with the pump power, 12 volt power and ground. I labeled those up and then decided where I would mount my monitor. I decided that below the wall outlet would be the most painless location and fished the wires to that location.



I then wired the supplied connector to my coaches wiring and was able to test that the water pump first to see if that working. I also wired up my LP tank which only required 1 wire, and since SeeLevel uses only one positive wire and one ground for all of the other sensors I tied these together and the wiring for the plug was complete.



Now came the hard part, (well I thought it would be hard) wiring up the fresh, grey & black tanks. The old system utilized 3 sensors & 1 ground for each tank. The 3 sensor wires lead into one wire which intern went back to the monitor. I clip the 3 wires off, and wired it to the blue sensor board wire on the SeeLevel system. Wired up the ground to the black wire and that was it! The sensor board by Seelevel has adhesive and is stuck to the outside of the tank. I thought to myself that was way to easy. I wired the other 2 tanks up and I was done!

Now here is the greatest part of this system. I have always wondered why motorhome manufacturers do not include a second monitor out in the sewer / water bay. You out there working with those tanks and you either have to run back and forth to determine what is going on in the tanks or you have to post a person inside to yell back and forth the information.

Since the SeeLevel system utilizes the same wires for all the tanks sensors I can easily tap into the sewer bay sensor wires add 12 volt power and mount a monitor in the sewer bay. No pulling wires!



I am really excited to have accurate reading on all my tanks this RV'ing season.

Nice Post. Thanks for taking the time to share what you learned.

I'll be anxious to hear how the accuracy is. I've been disgusted with my monitors since day 1 - they only show the level in 1/3 increments and rarely have anything to do with reality anyway. I've been looking at the See-level gauges but have never been totally sure they would actually work better than what I have.

I will be giving the systems a workout soon and will report back with how it performed.

I'm planning on replacing my old fashioned probe style gauges with the sealevel ones this Summer.

I've got to do a little measuring on the current panel since Winnebago integrates the tank monitoring system into the "One Place" panel. I'm optimistic I can remove the current portion of the One Place panel used for the tank displa, and mount the Sealevel gauge in it's place.

Another project to add to the list.

Bill the SeeLevel system just adds to that class coach of yours. The unit in the water bay is even better I wonder why MFG's never thought of that one, should be very useful. Which 709 model is it? "007"

I installed the first SeeLevel system about 6 years ago. I am now experiencing sporatic incorrect "100%" readings on fresh water, which is strange because the frest water tank is inside the coach. The other tanks work great and the indicated capacity (at least on 100% and 0 % are accurate.

I highly recommend it.

I've been running the SeeLevel system for close to 2 years now. It's a very accurate system and I'm totally sold on it. We have a smaller panel in the basement and the larger panel upstairs.

It is possible to get an occaisional errant reading off them. This typical occurs in a high humidity situation when condensation forms on the surface of the tank sending unit strip. Once this condensation cooks off, they read fine. The recommended fix for this is to apply some electrical sealant (clear silicone goop?) over the sender so that the condensation can't short out the electronics. They don't get hot so the sealant won't affect them as far as heat retention is concerned.
