New to Bluebird

[lajollacricket]

I currently have Hawkins that is powered by a 3208T, but am considering a
different coach. I've narrowed my search to tow brands, Bluebird and
Foretravel. Today, I looked at a 1995, 40' BB powered by a 8V92. The coach
could be had for approximately $70,000. As I am not familiar with Detroit, how
reliable is this engine? Any things that I need to be on the lookout for on
Bluebirds? What kind of mileage would be expected from such a coach? The
dealer told me 8 1/2 to 10, , but I find that hard to believe. My Hawkins gets
8mpg towing or solo. Some of the things I found very nice in the BB, were 1)
Roof mounted generator. 2) Exhaust on top of coach. 3) The rock solid feeling
the coach has while walking around in it. Thanks for all advise.
