On our 1991 # 277, when I ran the headlights, the dash voltmeter would indicate low voltage. However, the batteries always stayed charged. It would be really good to start engines/generator and check voltage at the batteries. If you have about 13.2/4 at the batteries, you simply have an indication issue. Newell might have installed too small a wire for the DC load to the front panel AND dash voltmeter. 40' of DC wiring has to be huge to only have a 3% voltage drop.
After switching to LED headlights, the voltmeter lowers some, but stays in the green. Good luck!
