I have no need for truck charging for my 2 100ah Battleborn batteries. The 400w of solar keep them charged up. In fact, I disconnected the truck charging wire at the camper converter, I wasn't sure how the AGM truck batteries would handle the 14.6v from the converter when I have the camper plugged in.
We also disconnected the truck charging wire at the converter, actually put in a switch always set to off. My system uses GBS cells with a dedicated "brain" unit (in addition to the individual BMS) through which all charging sources and loads run. Since the wire from the truck/converter does not go through this regulating brain, I didn't want to fiddle with it. When we plug in shore power (never), I disconnect my batteries for the same reason.
