Best Video Tutorial for De-Winterizing 2016 2400W

[hovey]

Hi - I'm still a newbie. After buying my 2016 2400W used in late 2017 (it was already winterized when I bought it)...I had a local RV shop de-winterize it last spring, and then had them winterize it this past winter. I want to de-winterize it myself, but I'm overwhelmed with the number of YouTube videos. Is there a video out there that shows a 2400W specifically? Thanks!
