I just purchased a 2006 Mandalay 40E a week ago. I had the exact same thing happen to me today. I "assumed" it was due to me leaving the inverter on for the whole trip. I was at a campground on shore power for 3 days, unplugged and drove home and my house batteries were dead. After plugging in for just a few minutes, the batteries were back functioning properly. Let me know what you find out, it appears we have the same issue.
1. Inverter is on the COACH batteries, the OP has a chassis battery problem
2. Plugging in to shore power, after a few minutes DID NOT fix your dead batteries. ALL you are experiencing is the Inverter/Charger is now charging the dead coach batteries. It will take 3 to 6 hours on shore to charge the Coach batteries
3. When driving, the Chassis Alternator charges the Coach and chassis battery banks.
4. IF the Coach batteries are boiled dry, then you will have dead batteries and will be running off the Inverter/Charger instead of the batteries. CHECK THE COACH BATTERY WATER. If boiled, they are destroyed, replace them.
5. IF OK, then determine if your chassis charging system is charging the coach batteries. Doug
