Dead batteries again

Hi everyone !!
You all helped me the last time on my generator issues, and it really helped !!
I have issues with my batteries again. I just went to start up our 2007 Winnebago Voyage, and either the engine battery is shot or possibly the starter as when I turn it on, it just clicks. I have brand new Interstate house batteries. The chassis battery starts the engine. Sounds like it's discharged and or bad.I couldn't even use the battery booster to start it.The control of the boost may use the engine battery. I keep it plugged in to 110 volt all the time. Also, should I leave the inverter turned on, or off?Inverter off and charger on. But with shore power you can leave the inverter on but all AC devices off.
I'm still a newbie, so any advise would be greatly appreciate. If your chassis battery is not charged by design there are various ways that can be accomplished including a small trickle charger.Thanks in advance !!
Sincerely,

Steve
