The number of tanks your RV monitor system can track makes a big difference in how well you manage water and waste. Most systems keep an eye on three to four tanks, usually fresh, grey, black, and sometimes a galley tank. The more tanks you can monitor, the less guessing you’ll have to do, which helps avoid messy overflows or running out of fresh water at the wrong time. For example, the Garnet SeeLevel II 709-4PH is built for 5th wheel trailers with four tanks and even shows battery voltage on a clear LED display. It also has pump and heater switches right on the panel. The Garnet SeeLevel II 709-4 is a great fit for motorhomes and campers, giving you the same four-tank monitoring with easy-to-read digital accuracy.
