My motorhome is on a Freightliner chassis and my chassis batteries keep going dead even though the coach is plugged into a 30am plug around the clock (while in storage).
There is obviously a draw on the batteries and for some reason, the house batteries are being charged but not the chassis.
Here’s what I discovered :
When I leave my chassis power on, the charger will charge both house and chassis batteries. I’m not sure if this is recommended but this is what I do while I’m spending the night in an RV Park or Campground. Now, when the coach is in storage, I turn off all power including the battery disconnects. I fire everything up once every few weeks and let it charge.
This works for me.
