My best advice would be for you to contact Winnebago Customer relations for technical help. They may have a service bulletin out for your coach. There could be a defective isolator circuit that the chassis side is drawing power when it should not. With that said. Recharge the batteries fully, turn off the disconnect and remove the cables from the chassis battery; both positive and negative for a few days and then check the voltage on the house batteries. Let us know what you find.
