Greetings,
New to the RV world as we just purchased a 2020 Winnebago Boldt KL. I have been reading through the manuals and trying to understand the workings of the batteries. We have a Volta system that powers the RV and a separate battery to start the engine. I am looking for advice on how to maintain the chassis battery as we have not driven the RV for a few weeks and had to jump start the engine yesterday. Reading through the manual it talks about disconnecting the main battery switch but then I hear folks say that is not a good thing. My understanding is the solar panels on the roof will help maintain the Volta system but will not help maintain a charge on the chassis battery. Plugging in the house 120v to the RV will only charge/maintain the Volta system likewise with the 30 amp shore power line. What do you all recommend for maintaining a charge on the chassis battery when the RV sits for a period of time? Thanks so much for your advice! Looking forward to enjoying our Boldt but have a learning curve to tackle first.
 
Put a battery tender on it.
