Load center wiring
Here's my question: If one were to disconnect the negative cable from the battery to the load center (fuses, breakers, etc) AT THE LOAD CENTER, shouldn't one have no power to all the 12v devices? ...

I'm not on shore power nor am I connected to the truck.
If I disconnect at the battery end, everything is unpowered as it should be.
I'm trying to find out if this is normal. I think it is because the negative terminal of the battery is connected to the frame ground as are the ground wires.
If you disconnect the battery, and the truck pigtail is not connected and there is no 120 v power, and you are not connected to solar, then it is normal that there is no power to any 12 volt device. If there were I would seriously wonder where the power was coming from.
The negative terminal of your battery might be connected to the frame. That is the way cars and trucks are wired. That is not the way my RV is wired. The frame is not used at all. In fact there is no metal frame, just wood. The negative wire runs to the power station. My solar is wired separately. There is a wire from the solar controller directly to the negative terminal of the battery. I also wired my NovaKool compressor refrigerator with a negative wire that bypasses the main electrical system and goes directly to the refrigerator. It was the easiest way to bump up the wire gauge.
