Are they the original Harris "dual purpose" batteries? If so they might be shot and won't hold a charge. My original Harris batteries gave up long ago so I swapped them for Trojan 6-volt "true" deep-cycle batteries unlike the original Harris batteries. Very happy with the swap.
Regarding charging, they
should charge from the converter and/or the chassis alternator. If they are not charging from the converter, check the 120-volt breaker for the converter and cycle it on and off to make sure it is actually energized. Also check the reverse polarity fuses in the power panel to make sure they aren't blown. Beyond that you could check voltages with multimeter if you have one and know where to check.
In your power panel, do you see a small green LED light (through a small hole in the panel) on or blinking when connected to shore power or with the generator running? It will tell you what mode the converter's battery charging circuit is using to charge the batteries. If no LED, you may have no power to the converter (check breaker) or a problem with the converter itself. But our Progressive Dynamics units are usually very reliable.
On my original Harris batteries, one developed an internal short. It would get physically warm just sitting there (not charging) and would drain the others in short order. Once charged with your external charger let them sit a while and see if any are warmer than the rest. And if you can get them individually load tested. I bet you will find out they are diminished.
