There are a lot of ways people use to maintain batteries. What I do during the camping season I wait until my batteries self discharge to 80%SOC then fully recharge them. In the winter storage season I fully charge when I winterize, disconnect the negative cables and the batteries are good until spring. Most batteries fail from under charging when sulfation builds up on the plates, but I think plates last longer(less lead shedding) if not left to charge constantly.

Not sure if this is practical in your situation but take the batteries with you and keep them on a trickle charger.

You need a good 3 stage converter in the RV to prevent overcharging when on shore power.

When plugged in the chassis battery does not get charged, only the house batteries.


Careful about oversimplifying - our Tiffin came from the factory with a trickle-charger connected to the starting batteries, so they definitely DO get charged whenever the bus is on shore power.

Electrical systems vary all over the place from brand to brand, and model to model. It's hard sometimes to make blanket statements that apply to them all for some aspects of their design and capabilities.
