Charging issues?

Not wishing to highjack this thread, but I have related question and thought it would be better to put in this thread instead of starting new one. Stored my Tiffin for 30 days in Georgia and was very careful to make sure both chassis and house batteries were shut off. Inverter off. Was unable to get any electricity for charging due to storage facility. Coach started right up, but NOTHING worked off house batteries. (4 6v, golf cart batteries). Not even dome light would light. Had to use emergency "jump" from chassis side to get generator going and charge house. Drove straight to campground. Have not checked battery charge since plugged in. 2 questions;

What the hell killed my house batteries? Any idea what could bleed them to death in 30 days?
Will they have useful life for a little while? They are original in coach and probably 2 yrs- 3yrs. old.

Thanks

Healthy battery should be fine for 30-90 days if truly disconnected and fully charged. Unfortunately it will be up to you to discover if the "disconnect" switch actually disconnects everything, verifying the state of charge before and after, and how they perform after the fact.

As a very minimum we would need some actual voltage readings...

Nothing wrong with starting a new thread no matter how trivial. Copy-paste your post into a new thread is fine.
