Yes. A lot of Class B’s are set up that way, including my Winnebago Travato. At least mine has an emergency start switch that can connect the chassis and house batteries. The engine alternator charges both the chassis and house batteries but shore power and the generator only charge the house batteries. There must be some system in these type of configurations that disconnects the house and chassis batteries when the engine is turned off and then connects them when the engine is turned on. Is anyone familiar with what system does that and how it works?
