I've bought two RV's so far and both times the service person was very good about answering questions. The second time was faster, as the guy was moving along, and I knew more than the first time, but he always stopped when I asked questions. He said at the outset that he wanted to spend as much time as I wanted to and that he hoped I would have a nice comment to his manager. So he he was motivated to make sure I was happy.
Like others have said, I'm sure the service and/or sales manager would like to hear about your experience. They get a lot of business from word of mouth.
