in most RVs the starting battery is not charged while plugged into shore power. we've used this for the last 10+years to keep the chassis battery charged while parked.
beyond that you need to be sure your chassis battery is capable of holding a charge.
if the battery is a typical lead-acid 'wet' type i suggest disconnecting the battery from the RV, putting it on a battery charger for 24-hrs and then disconnect the charger and allow the battery to rest for about 30-minutes. using a hydometer check each cell. if the battery tests good but is not holding a charge when connected to the MH the MH charging circuit may be faulty.
you can also take the battery to just about any auto parts store to have it tested.
