Yes, buy a digital voltmeter (starting under $20).
Tell us what the voltage is at the batteries. Read at the positive terminal with the large-gauge cable going to the RV. Other lead on the negative terminal with the large-gauge cable going to the RV.
Also, tell us what converter, charger or inverter/charger you have. Many are programmable.
Also, with eye protection on, shore power and generator off, check water level in the batteries-- they may be overfilled.
And, while doing the water check (be sure to use distilled water), an excellent under $10 tool to check battery condition is a BATTERY HYDROMETER from any auto parts house. If you want the real story on the batteries, let us know the hydrometer readings on the individual cells.
