That's a Forest River product, correct?
If the batteries had a 8 volt charge, you've shortened the life considerably. If they were at that charge for any period of time, they are probably ruined.
You need to get them charged back up. Is there any on site power available you can plug in an extension cord for battery charging?
Another option is to take the batteries out and take to a local store that can load test them for you. If you go this route, be sure to take lots of pictures of the battery connections so when you re-install the batteries, you connect exactly the same way the first time.
If power is not available when in storage, you're going to need some sort of battery disconnect that disconnects everything. I don't know what FR put on there as OEM. You might need a mobile RV repair person to come install something for you. Possibly adding solar would be an option as well.
