its Normal for the alternator to charge EVERYTHING, either thru diode base isolator or heavy duty charge relay (any MH that does not charge the house from the alternator has a problem that needs to be tracked down and fixed)

it is also very common for the 120v charging circuits to only charge the house side RV batteries
some MH's have a Bi-directional charging for all batteries from either source
but it is NOT common
