What can you do? I hope you have documented your problems, at least the big issues, a letter to Grand Design with those problems listed and your dissatisfaction with them couls jog a few responses! Most all comments on the lack of quality in RV builds are right on, but the one thing I saw when researching my buy was that Grand Design went out of their way to try and make buyers of their products happy with that decesion. A good well thought out letter, with issues and dates might spark a response. Good Luck!
