It’s simple. Two screws in the back, accessed from the hatch, two screws in the front, below the door (open the door). Hardly worth the effort to create a video on it. Push it out the front, disconnect 12v,
propane and 120V first.
Except for a few rare examples, people creating videos do it for free. The monetized YouTube sites tend to focus on bigger tasks that attract more eyeballs.
