First thing you should have is a wiring manual for your truck, before any electrical troubleshooting can be performed.

 The front will ground at the lights. If the hood is not grounded to the frame it won't turn on.

 Check your fuses, it should be label Tail/Stop/Dome. Dome light come on when the headlight knob is turn full bright. There should be a detent in the switch when it turn on. For it to operate by the doors a switch will need to be added to both door frames between the hinges.

 This sound more like a bad ignition switch. It should operate in run and ACC position.
