As in an automobile, I expect a certain level of quality, whether it is a $16,000 Dodge Dart or a $100,000 Mercedes S Class. I don't think the electrical system should have a burn out within 10 days of use, I expect all the doors and windows to be properly sealed, I expect the radio to work and not have wires almost cut in two, I expect the radiator to not leak, etc. even in a Dodge Dart. Why should I expect anything less in a $100,000 motor home? Not everyone is going to purchase a Prevost, but you expect some quality checks along the way.
I also expect when I purchase a new car that the salesman or other person with the dealership to be able to show me all the bells and whistles and how they work.
