Camper AND truck batteries dead
So Ive been pretty proud of my recent solar upgrade to the camper, but haven't really had a good workout with it. Fun just knowing everyday the batteries are being topped off and floating due to sola...

Even thought I have a TC and my battery isolator works fine, I still unplug my truck from the camper when it sits and length of time. Better safe than sorry.
Your batteries may come back and they may not. Flooded cell batteries don't like being discharged past 50% of their capacity and heavy discharge usually (but not always) results in decreased capacity and plate sulfation. All depends on how old the batteries are and how many times you discharged them below 50% capacity.
I run a SeeLevel battery monitor on mine so I can tell at a glance the state of charge as well as the battery temperature, which is an important consideration because when you have a heavy charge rate or discharge rate, the batteries heat up from the chemical reaction. I like to keep them as cool as possible by limiting the charge and discharge rates.
I have a battery monitor as well. Unfortunately I didn't look at it for the 2 days the camper sat there as I wasn't using it. The batteries DO seem to be coming back up, currently at 9.6, being charged by the converter. It's only been a few hours since I discovered this, and it's dark, so no solar charging currently. The batteries were new this year, and have never been below 12.4 volts since I installed my panels and charge controller.
