First thing to do is to make sure your battery is good. If you don't have a way to test it, take it to a parts house like O'reilly or Autozone and have them test it for you. If the battery is good, than you need to do a Parasitic drain test on the battery to see what is draining the battery. You will need a multimeter that will be able to read amps. If you have one or can get one, than you can do the test. Here is how. Disconnect the Negative battery cable from the battery. Leave the positive cable connected. Now, put one of the test leads from the meter on that loose cable. Put the other lead from the meter on the negative post of the battery. When you do this, If there is no drain on the battery, the meter will show very little movement on the scale, maybe 50 MA. If it shows a high reading, than, something is draining the battery. You can now go to the fuse box and start removing one fuse at a time until you find the circuit that is causing the problem. While you are removing each fuse, have a helper look at the meter and when the meter scale drops to O or so, your helper can tell you that it has dropped to 0. When doing this test and you find out that yes, you do have a drain on the battery and before you get inside the truck to check the fuses, make sure to disconnect the meter from the battery post cause if you don't you might damage the meter when you open the door or if you turn the key on. If you are not familiar with the meter or don't know much about electrical , maybe you have a friend that can help you. Hope this helps you.
PS- When doing this test, put the meter on 10 amps scale.
