I agree with jayfowler - I made good use of YouTube and Google when we bought our first camper. We also did our first overnight at a local campground with friends who knew what they were doing.
It is overwhelming at first, but it will become habit after the first couple of trips.
One tip I will give you - make yourself a departure checklist. It will help keep you from pulling out of a spot with the antenna up, shore power / water still connected, etc.
