Take a video of the instructions you get for operating every system. I will assure you that you will not remember some small, important detail. Your success at this is directly proportional to how many calls you have to make or posts on this board to ask how something works after you were given prior instructions.

I sold my first coach to some folks that I painstakingly walked thru every system and nuance of the bus. Did they tale notes or video? Nope. And a gazillion calls or trips to the RV park to go over it again. I was okay for the first week but was less happy after that.

I took someone with me for the last two. We started to video when we determined we knew more about the coach than than the owner. Not good.
