You should identify the year and model of the coach you have or at
least the coach prompting the questions. I believe all of the DD 2
cycle engines, series 53, 71, and 92's have roots blowers (or
superchargers) whether belt or mechanically driven, as they won't run
na. Turbo chargers are in addition to that blower to increase hp
ratings and some of those turbo'd gain further boost with after
cooling.
Most motorhomes employ inline configurations with the transmission
bolted up directly to the engine, both ahead of the driveline to the
drive axle. (or behind dependent on view of a pusher) Exceptions
could be "converted buses". However all Birds I'm familiar with have
the engines configured to inline.
I hope this covers your basic questions and if not, e-mail me direct
for further elaboration.
