There should be a charger on-board that may need attention or replacement. if there are some smaller wires connected to your neg & pos battery terminals see if you can follow them to a charger, but they might not be there as they could connect thru the solenoid. If you can find the converter (converts 120 vac to 12vdc) the charger could be included with it or separate and located nearby. I would expect it might be one unit, but maybe not.
Also, when you say coach batteries I assume you mean the batteries that power your 12vdc lights and accessories, not the chassis battery that starts your main engine. The chassis battery is not charged from shore power.
Hope that helps.
