If the truck is not started everyday the battery drains. I tested everything even pulled the fuses out, but nothing is helping.

Did you have the battery load tested? If the battery is shorted internally, it will drain itself.Also, did you do a parasitic draw test? Use an amp meter and remove the negative cable. Install the amp meter leads to the battery and the cable. Let it sit for one hour and then check the reading. It should have only 50-75 milliamps of draw.
