DC power issues- any advice?
We have a 5th wheel with two 6-volt batteries (6 month old Interstate) hooked in parallel and a 6 month old Intellipower 9200 converter. Power issues are fine when generator is on or when hooked to s...

First I think you mean the batteries are in series, not in parallel if they are 6v.
It sounds to me like a bad battery. Hard to imagine how such a low current draw could deplete the batteries that quickly. With the cells in series all you would need is one bum cell in one battery. I would check the specific gravity of the cells. Any auto parts store should be able to do that.
If it were starting low and staying there then maybe a bad connection, but you say the batteries are draining.
You should have a couple hundred AH of power. It would take quite a load to deplete a good battery that quickly and I'd guess you'd know about it because something would be cooking.
Yes- they are in series. Without fridge on- batteries hold a charge. Sometimes when we get low power inside, when we check at the battery- the charge is fine.
you may be seeing a surface charge when there's no load. As soon as you try to use them they are dropping quickly as I understand your post. IMHO a connection problem certainly can cause a high resistance and therefore low voltage, but unless that connection is heating up drastically I don't see how the voltage would change that quickly.
