Sorry I don't have a departure checklist. But, I do think it is a great idea, especially if you are new to RVing. It can stop that embarrassing moment someone waves you down because you forgot to put down your antenna. (Yes, it happened to me.) Or forgetting to raise your jacks. (I was so lucky that my jacks just go down to the axles and not the ground. I would have had major damage if I had the ground leveling jacks.)
You could use a checklist like

On Edit: sorry for the very clumsy url but I apparently do not know how to use the url references on this forum. (It is much different than others.)
