I have replaced the battery, had the alternator tested, made sure every light was off, every door closed, every extra thing is off. After a few hours or a day or so I go back out to start it and it’s drained again.

Hello,

Sounds like you have excessive parasitic draw on the battery, causing it to drain.
Keep in mind the draw can happen for any lights staying on as you have already checked, but also for any number of faulty electrical components. Like a shorted switch or faulty radio etc.

Take a look at this video, it goes over how to determine what is creating the battery drain:

Let me know of any questions.
Thank you.
