Here are some thoughts from a deranged mind; given the characteristics of lithium batteries and the abilities of modern electronics to monitor and control what they do to have just one set of batteries for both the house and chassis. Knowing the outside temperature should provide enough information to limit discharge to the point that leaves enough charge to start the drive engine which also insures being able to start the generator. It occurs to me that my chassis batteries probably never get discharged more than 5-8% except in cold weather and its capacity is largely wasted.

Also, the Roadtrek eTrek eliminates the separate generator and uses the main engine to drive an enlarged alternator that through an inverter supplies the necessary 120v juice. Maybe some version of this would work for some us depending on how we use our coaches. If we aren't using our generators alot then this setup would not be hard on the drive engine and would overall be more efficient.
