I have a friend who just also bought a Vegas. He also has problems with both chassis and house battery going dead after only a week or so, even with the kill switch off.
I usually have 30 amp power to the RV on since I park it at home and only the chassis battery goes dead. but if I do not plug the RV in, both batteries go stone dead in a week or so. The batteries are so dead I can't use the emergency start to start the engine off of the generator.
