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...

Leaving the camper hooked to the truck should have kept it charged with that much solar. Are you sure your solar system has output? I'd look for a blown fuse, bad connection, fried charge controller, or something like that. With a Chevy the truck plug is always live so the parasitic loads in the RV drained it too.
Agree, that much solar really should have maintained all the batteries. Somethings wrong.
My RAM's plug is always live too. So I was thinking to leave the truck plugged in deliberately so my trailer's solar can maintain both the truck and trailer batteries during long-term storage.
The truck has so many parasitic loads itself that, according to the manual, more than 3 weeks storage is bad for the batteries. Found out about that the hard way last winter when I killed both of the truck's batts with 7 weeks storage.
BTW - can a solar system work in "reverse" and drain the batteries?
The panels are supposed to have diodes to stop that. And I would think the controller itself should prevent that as well.
