Maybe with generator running while driving causing this.
FINALLY!
This is probably it. If the coach is set up to charge the chassis battery while parked, that same setup will try to charge the battery any time the generator is running. If the voltage it's applying is greater than the alternator voltage, you'll get a light on the dash.

If the battery light is on a STAYS on after multiple re-starts and driving, then you DO need a new alternator.
12.5V on the battery after resting overnight and before starting is a little low. I think I would be more concerned about that !
