Absolutely, I'll certainly do what I can. What voltage does your Battery bank voltage rest at with no load or charge after 4 or so hours? If you over discharged your batteries as you said I would equalize them per manufacturer instructions. This is essentially a controlled overcharge that will help de-sulfate your batteries. I recommend you do this as soon as you can
As silly as these things seem, customers say they really work great at circulating the cold air throughout the refrigerator compartment, and that helps to keep the food inside evenly cold between the upper and lower shelves.

To be honest I'm not sure. We tend to have at least some small load on it here and there. I'll make a point of letting it sit with no load for a while and check the voltage. And we met up with some other travelers that happen to have a charger with an equalization setting which we will use very soon. Thanks. I'll let you know how things go.
If I recall you have a duracell AGM battery which is a rebadged deka I believe... be sure the charger does not raise the voltage beyond what is recommended for that battery, I suspect you will have to find that info via Deka as opposed to Duracell. Think you can find me one of those sweet truck campers? lol... How are you liking the truck your using?
