Lotta possibilities here, including the advice to find the "drain" on the batteries.
Look back at probability of that though. If nothing was draining the batteries a few months ago, what have you done since, that would?

I'll list a bunch of stuff to be mindful of or check
1. "New" alternator could be bad. Strong chance if it actually, assuming it's a reman alternator. If since the alternator, you only drive it a few hours, could be enough juice used to kill the batteries.
2. Dead battery doesn't necessarily mean it needs to be replaced, although deep discharge doesn't help the longevity. Do you not have a simple battery charger and somewhere to get power from?
3. Disconnect house battery and run it (with start battery charged). Does the starting battery go dead without being hooked to the "house?" And vice versa. Charge house battery, disconnect it from the isolator and does it just go dead or not?
4. How hacked up is the electrical in this unit? The more jerry rigged it is, the more chance of an errant power draw or bad connections, etc.
5.

Call some RV repair shops and ask for the number of a good RV electrical troubleshooting/repair guy. This may cost some money but may solve the problem quickly. You will eventually learn how the chassis alternator charges the house battery(s) and chassis battery while you are driving, and how the converter/charger converts 120vac "shore" power to 12volts to charge your house battery(s) and power your internal lights, furnace blower, fresh water pump, appliance controls, and other 12 volt DC items. Not simple but critical to enjoying your RV.

Try to find a good RV electrical systems technician. Some RV repair shops can refer you to a good one. This may save you a lot of frustration and get the problem(s) isolated and corrected quickly. Watch what the tech does and you may learn from it. Good luck!

Hi everyone. Ole girl is back on comms [emoticon] Sorry for the delay as the past month has probably been the most difficult of my life. I'm settled now full time in my RV at a park. I wanted to thank this community for helping me trouble shoot this and let everyone know that the problem was indeed a bad isolator. Hope this helps anyone who is having the same issue.

Sorry again for the delayed response.
