thanks for the great intel colorado, I think it's dead on the money. This bus has 37K on it & the only obvious problem anyone saw when it came in was 1 of the front tires wearing a little funny. They are replacing both steer tires & having it aligned. I'll ask about the bushings and the roof today. Bushings should last a lot longer than that. I wonder if they were low quality or there's some kind of ongoing problem?
