DC to DC charger question

Did you use a trik-l-start + amp-l-start or just an amp-l-start?

House battery --> trik-l-start --> chassis battery --> B2B --> House battery .............

How did you avoid a loop? Manual switch(es)? Amp-l-start's higher on/off voltage trigger? Victron's on voltage?

An Amp-l-start back to back with a Victron Orion Smart B2B. Wired directly, no manual switches. The trigger voltages on the two devices don't overlap, so there is no loop.
