With or without trailer. Lights stay on if parked or engine off. As soon as you start driving the circuit gets overloaded and trips. The woring appears to be good nothing rubbed at pinch points etc.

on the back of cab, a wire strand may have come loose

and touching to ground

as you Know , electrical is hard to find, it is al trial and error
