Charging chassis batteries
We have a 2012 Allegro Breeze DP. We've had a few problems with it since we bought it but nothing as big as this. We were out of town last week and left the RV home without plugging in to house power....

You would be wise to check battery voltages while you are charging to see if your batteries are actually getting the voltage from the converter.
You may also have a Bi-Directional Relay that is stuck in the closed position. This relay allows charging from either side to flow to the other side. Normally, the chassis battery while running charges the coach via an isolator, but with a Bi-Directional Relay if the coach battery is higher than the chassis, charge will flow that way.
I had one once that stuck in the closed position. Any drain from either side would then drain all batteries equally. In a week, you can lose a lot of parasitic power... did you leave a fridge running?
Check voltages, see what you have with no charge voltage, and what you have while charging. A meter tells a lot.
