Something is killing the battery. The truck has not been able to crank since October 6, 2016 that is when I replaced the battery with a new one. What could be killing the battery? What all do I check?

Take it to an auto parts store and have them check the charging system.

You may need to reset security system or try another key. Also check battery it still cold be bad. Then it has to be checked for a parasitic draw which all vehicles will have some.

Check door switches then scan for codes as it may be a body module problem. A mechanic will need to do this, which why you should send it to him to see why it wont start as you say you have little knowledge.
