I'm on my battery charger now, and it shows about 5% charge on the battery after an hour. This had metotally frustrated.

If you put a volt meter on the chassis battery when under shore power or generator, it should read the same charging voltage as the house batteries - at least mine does. That means to me that they are being charged at the same rate. Are you charging using your internal converter charger or an external battery charger? What voltage do you see on both battery banks?
