Same coach as you. I assume the alternator is supposed to top off the house batteries. What are you running off them in route? if there is too much drain, maybe the alternator can't keep up.
They aren't connected except for the fact that if the main is to low to start the engine, then the dash battery rocker switch is supposed to link the house batteries to start the main engine but I don't think it works the other way.
We usually have folks with us and run the generator while we're enroute...The inverter was removed from mine when I got it and it's Florida so we need the ACs.
