The problems exist whether you buy a $20,000 trailer (or less) or a $2,000,000 Prevost (no that number is not wrong). There are so many layers of "quality". Is it the problem with the chassis, the converter or the manufacturer of the hardware. There are so many people involved and so many people responsible for the various parts and components it's impossible to expect a perfect coach coming out of the factory. I would not expect the car I drive off the showroom floor to be perfect either so I am not sure why this seems to be such a point of contention.
