Keeping Chassis Batteries Charged
Check out this inspired solution from an experienced RVer:
I keep our motorhome plugged in when it’s not being used so the three-stage inverter/charger can maintain the house batteries charge. This works fine, but when I cover the coach, the solar panel for charging the chassis batteries doesn’t work very well. To fix this problem, I put a short jumper cable between the 12-volt positive terminal of the house batteries and the 12-volt positive terminal of the chassis batteries. I made the jumper using two car battery clips connected with paralleled 10-gauge insulated wires.
Now all batteries stay charged. I put a labeled clothes-pin on the steering wheel to remind me to remove the jumper when the motorhome is put back in service.
