OK, I gotta ask, what is the intended purpose of being able to open and close the forward shutters?

Is this a consideration only when the bus is in motion? Does it allow any fresh air into the coach or only provide ventilation to the forward Cruise Air unit?

Are there any concerns with having the shutters either opened or closed when travelling?

Seems the Liberty manual makes mention of using them when the forward Cruise Air is operating, but only when moving? Or should they also be open when parked and using the Cruise Air units. Closed when using the OTR air?

Is all of this temperature dependant?

Anyway, just thought I'd ask......
