2019 Thor Class C. We have two batteries. After three days the indicator showed only one light. 1/3 full. I tried to start the generator and everything went dark. The generator wouldn’t even crank. I guess there was not enough juice left to start it but now all the 12 V is dead. I ran the engine for a half an hour but nothing has changed. All the indicator lights are dark even the tank levels and lpg level.
3 days is plenty of time to drain 2 batteries. Heck, you can drain them in a day or less if you have a lot of things running. And as the OP said if you read their response, they had some loose connections.
You're not alone. I've been RV'ng for 20 years and more than once been caught by the dead system attributed to loose wing nuts. Now I try to remember to check the nuts every time I hitch up or unhitch at camp.

Not sure if this is really a question. You ran the batts dead. Not much help for that other than plugging in or getting a jump on the genset. Although the electronics on the ONan require battery power to keep the circuits running to maintain the fuel solenoid. A half an hour is not much to re-charge completely dead batteries. And deep cycle batteries when run down completely usually are never able to recover fully.
This morning I looked at the batteries and wiggled the cables. I heard a beep as the refrigerator turned on. I tightened up all the wing nuts and everything came to life. I have it plugged in to shore power now. I would like to apply some contact grease between the cable ends for a good connection. What is a good product for that?
Go to your local GM dealership and ask the parts folks.

Did you remember to connect the house batteries with the switch. The generator on Class C's runs off the house batteries, and they need to be connected to charge off the engine.
