Tried alternator, was fine, checked all fuses, and replaced the old battery with a brand new one. Now last night i decided to return the battery with a new one. After puting it back on last night i decided not to start it so i could see if something was running it down with the truck off. So i gave the horn a beep and turned the lights on to make sure it was hooked up. Waited about 12 hours and now its completely dead again. Any ideas of what may be wrong or running while the truck is off??? By the way this is completly stock truck. PLEASE HELP!!!

Well, you've got parasitic drain on the battery. You need to locate the drain or short, and in my experience that can be a pisser!
Start by checking with a VOM at the battery terminal and hot lead clamp to find out how much current is draining. To measure amps you need to read in series with the battery and cable. So you need to remove the clamp and probe between the terminal post and the clamp. Depending on how many amps or milliamps is draining the battery, you can get some idea as to what the source might be.
