If you mount the controller with the truck, then the truck is just a "solar suitcase' basically. My solar suitcase with controller connects to my batteries when I want it, and when I disconnect no harm comes to the controller. If you are going to be switching between 3 different trailers then using your truck like a solar suitcase would make more sense to me. Some solar suitcases are using 20' of cable from controller to batteries.
Never said it "would harm" anything if connections are made in different order.
However, some controllers are designed to detect if battery voltage is present before it will pass the solar panel voltage to the battery terminals of the controller.
In those cases, no battery voltage detected=no solar panel voltage passed to the controller terminals..
Real cheap controllers without adjustable parameters or without wide panel and battery voltage most likely won't care, more expensive controllers with adjustable parameters and wide panel and battery voltages may care.
