I turned the key had all start functions, truck went click. Tried to jump start and now the truck is totally dead. No nothing,no dome light, nothing. Dead. Any ideas?

 

I will say check all fuses. If all fuses are good start checking cables and wires and start checking connections for a lose connection if all connections are good. Time for new batteries. But good luck. And who knows. I could be wrong. Correct me if i am please people. Learning is good.
