I heard back from Renogy today. I was correct in my assumption that their DC to DC chargers effectively isolate the house and chassis batteries since current can only flow from the chassis to the house. The typical setup uses a lead from the ignition side of the chassis electrical to turn on the charger, otherwise the charger isolates current from both directions.
If I proceed with this concept, I loose the ability to charge the chassis battery from the house side and to jump the chassis battery. I gain the ability to limit load on the alternator if the house batteries are fairly low and demanding a lot of current. I also gain the ability to charge the lithium house batteries according to their profile.
