My first winter I lost my coach battery due to a faulty GFCI outlet that I had the motorhome plugged into.
I replaced the coach battery with 2- 12v batteries and a permanent 100 watt panel, also added the trik-l-Start charger for the chassis battery.
The second winter the 100 watt panel, kept all 3 batteries maintained.
Note: We didn't have much snow this past winter.
I also added the Flowrite 12v battery watering system. This makes it easier to maintain proper fluid levels in the batteries.
