House Vs chassis charging

Just some additional information. My MH battery control center allows the chassis batteries to be charged when the chassis battery voltage reaches 12.6V. Until they they are isolated. You should have a battery voltage indicator for both. Should indicate above 13V when plugged in for both batteries.

Lots of good advice above! People are giving you advice about their rigs. Different motor homes are wired differently. I see you have a Ford with Scamper - 460 gas motor RV Year 1986.

You may not have a system that charges the chassis battery from the house system. In this case, a trickle charger may be necessary.

Checking battery terminal voltage is a good idea. Charging voltage starts at the resting level and rises to 13.2, 13.6, or 14.4 volts. A low capacity charger takes a long time to rise. A fast charger should reach 13.2 in less than four hours.
Lead acid batteries need to be stored fully charged.
13.2 is ideal for long term storage.
14.4 for long periods is too high.
Below 12.4 voltage in storage needs an immediate full 14 hour charge to preserve capacity.

They state that they have a 2018 Baystar in the original post.

oops, I missed that. "CP / About me" says something else.
