I think my engine batteries are totally isolated from the house batteries. Driving down the road the engine does not charge the house batteries and the generator does not charge the engine batteries.
When stored in my garage I keep the unit plugged in and I put a battery tender on the engine batteries to keep them 100 percent. I would like a way to charge the house batteries while driving, I'm thinking of adding a battery disconnect and connect them together, then I can shut it off if needed and I can turn it on to start the generator if I drain the house batteries too far down.
