Hello, I'm Danny.

That can be 1 of 2 things. Depending on how old the battery in your truck is then the battery may no longer to be able to hold a charge. Number 2 is if the battery is still good but just discharged then the alternator is bad and not charging the battery back up while you are driving with all the accessories on. Both the battery and alternator can be tested for free at any of your local auto parts stores. Here are a few tutorials talking about battery and alternator testing including symptoms:

The first thing I suggest is to take your battery to your local auto parts store to be charged and load tested. If bad you will need to replace. If battery tests good when you re-install make sure the connections are clean and tight. After this I would then suggest having your alternator tested. Let us know what happens and we'll go from there. Hope this helps and thanks for using 2CarPros.
