So when are you guys turning the battery switch to the off position? I’m assuming that this function prolongs battery life?

Although this post is several months old I will comment just in case you might not have figured all the details out. I have 2020 Bambi (but mine completed Feb 2020) and went through all this with AS Customer Service and their engineers and with Atwood regarding the propane detector. The CO detector is now 9v battery, so not connected to main batteries. When you turn off the main battery disconnect it also turns off the propane detector. If you have the stock Atkinson charge controller and a roof top Zamp those are able to charge directly to the battery while in storage. With this and the main battery disconnect turned off the only real drain on the battery is the solar charge controller, but that is being replenished when being used to charge and monitor batteries. When I go to my AS in storage and go inside the Sun Explorer II always shows 100-95% charged. But at 12.8 or 12.9 volts. As I understand, best practice for the Lifeline AGM batteries is to go into float in the 14.2 volts range. That is why many folks change out the somewhat rudimentary Atkinson for a Victron 100/20 or 100/30 MPPT charge controller. It apparently keeps the batteries more at full capacity level.
