I have seen a rise in voltage to 13.6 so far today. A few more hours of NE sun to go. Attached is a photo of Victron app history. IMG_9095.JPG
This to me would indicate that everything it working as it should - 100Ah at 13.2V is 1320Wh - over the past four days you have harvested ~1100 Wh, so you are most of the way charged. By tomorrow you should be full.

I’ve not followed the build but I thought to question the BMS or if the cells were all the same generation. That seems to look fine. Is the Camper connected to your truck system? Here’s pics with all power off for 2 weeks. Note ... not an electric guru.

I have a Blue Sea separator... the switch turned on but the button on top not pressed in. This I believe ...had the truck and camper battery separated.
The next day the juice in my camper battery was way low.
The camper now is not attached to truck electrics. The day is partly cloudy and fridge on ... battery 13.36.

That smacks of similarity!... Though being a science guy I will not assume causality until I poke around and isolate the variables. I really do think the separator is somehow responding to the truck computer system at night (I have a couple things plugged into the truck cab usb ...GPS etc... that I know at night is still on...though minimal draw) ... wonder if the truck senses and draws camper battery at night? ....
I see no reason really to keep the truck and camper connected with the solar charging my camper. But that is a statement from someone who definitely does not have all the answers! Thanks for the input.
