You did not specify brand, model and year of motor home so it's difficult to say. You also didn't say if you have normal 12v functions like lights, vent fan, etc. If not, then your problem may be the battery disconnect switch is either turned off or faulty.
Are you talking about your engine batteries not being charged or your house batteries? If it's engine batteries, not all motor homes have a charger for those when connected to shore power. You can add something like the Trik-L-Start to charge those when on shore power.
If it's your house batteries that are not being charged, check the voltage at the batteries themselves. You should see the same 13.7 volts that you have at the converter. If not, then you have a connection problem somewhere. It could be in your battery disconnect switch, a bad battery connection, or a bad ground.
It sounds like your converter is working okay, so that's probably not the problem.
Battery water should be above the plates and just below the bottom of the filler holes.
