Like I said I drove my 3208 from Denver to Seattle and the only time
I had any real problems with speed and that would be coming out the
Columbia Gorge. I helped Dave Beatty drive his 83 back from Utah and
as far as
I could tell yes there was a little difference but not 70%. One thing
you haft to remember about these coaches that they are big heavy
machines and whatever mountain you come up to its still going to
become a slow haul if the grade is steep enough. I like the idea of
the retarder and kind of wish I had one. But then again this old
coach has 148,000 thousand miles on it and its still going strong. Jon

By the way does this coach belong to Steve? If it does I bought my
coach from him about year ago now.
