Sir I can help you with this, I have all the service manuals on your truck and will provide anything you need, but this honestly sounds like a bad wire connection or ground on a primary battery cable. I would trace all my battery cables and clean every connection even the engine ground cable and the one at your starter. I will be glad to help you further, I can post step by step trouble shooting guides on your truck if you need them. Hope this helps.

Also, to add to some mild confusion, the terminals under the hood on the charger are just there for a jump, thus there is only a positive terminal. The battery is actually stored in the trunk next to the spare.

Check the battery +12v power connection to the starter is in good order,
Check the ground connection between the battery negative and the engine/starter motor is robust and intact.
If no problem with above, replace the starter motor.

Charging the battery is pretty straightforward. Connect it like yo said. If the battery is no good, it will not accept the charge, no matter how long you leave the charger on it.
