Tank Gauges
Pressing a small button under each indicator lights up the display to show the water level in each
holding tank and the approximate voltage level of the 12V DC power system. The Gauges give a very
rough indication and can be affected by how level the coach sits, and other factors.
Water Heater Electric
The dual-mode water heater can be operated in electric-only mode, LP mode, or both at the same time.
