The orientation is informative and a lot of fun. You get to look around the shop, meet some of the people that built it, and you learn about the stuff that is specifically on YOUR trailer. You can ask questions about specific ways yours is built, things you might want to add to it, recommendations on maintenance, anything you want. They also hook it up to your tow vehicle and make sure every thing is compatible and working. Also you get a tutorial on how to register it in your state. Yes, you can learn most of it from reading or a video, but the personal interaction is enjoyable. We traveled from California to Wisconsin to pick ours up and I don't regret a single minute.
Oh, and don't forget to ask about where the best place is to get fresh cheese curds.
