There is a battery merge switch on the dash. When it is manually turned on, the house and chassis battery are tied together electrically so the inverter will charge all 8 batteries either from shorepower or from generator power. Starting the engine automatically merges the chassis and house batteries together so the engine alternator charges all batteries. If you keep the battery merge switch turned off, it is possible to have the chassis batteries run down it you are on shorepower for an extended time (weeks). I use an LSL Amp-L-Start which diverts current to the chassis batteries when the house batteries are being charged and the chassis batteries are at a lower charge level than the house batteries. That way, I don't have to remember to turn the merge switch off and on.
