If it has ABSOLUTELY no lights of ANY type at the rear of the truck, either there's an open ground or one of the connectors in the harness that runs from the front to the rear is disconnected or the harness has been damaged, as in cut or ripped out.
Otherwise, it would require MULTIPLE simultaneous failures of SEVERAL circuits to duplicate the symptom. Not impossible, but, if the failure is known to have occurred at the same time, look for a single point of failure first.

My opinion would be to print out the wiring diagram.then i would look for the headlight switch 5v lead to computer jump that to see if the lights come on.you are basically fooling the cputer to directly turn the lights on.the headlight switch is just the sentry in the middle.if lights come on after jumping the 5v signal wire to computer.(WARNING if you jump the wrong wires you WILL FRY your computer.gl.)Replace headlight switch(usually on the column with turn signals)
