Thor Super C (Chateau/Four Winds) improvements and mods

Interesting...two things I am vigilant on drivetrain and slide issues. I am assuming the drivetrain noise is more than a subtle sound as I only hear sounds I consider regular truck noise. Did they show you where it was installed incorrectly? Could you take a picture? Regarding the slide, so far so good. However, I do remember when I first purchased the coach the dealer put the slide out without leveling jacks down...granted the ground looked close to level...but I remember thinking why not do it right?
