Guess I'll have to disagree with that one. While some high end manufacturers choose high end shocks, many chassis have their shock choices made by the bean counters or go with corporate partners.
So, the OE MAY be the best shock available for your chassis/coach, but it could also be a much less expensive/much less desirable one.
