Black an gray tank monitors

[SEAYALL]

Has anyone ever done an upgrade to a better monitoring system that is accurate

[bikendan]

Have yet to see any tank monitors, even upgraded ones, that could be considered "accurate".
Seen many install Horst probes but even those aren't always accurate.

The see level 2 system by garnet industries is 100% accurate 100% of the time. Our 2017 Roo is the third trailer I have put them on. Easy to install but you have to be able to get access to the tanks to install the senders.

I to have used the see level 2 on my old toy hauler. Works great. Have not yet put them on my ceder creek 38el. I will as soon as I can get under it and figure out how to remove under belly covering.
