Roof or basement AC

[Bob Lawrence]

My bus came with both.
When running down the road, we start the genset,close off half the
bus and run with the roof air. It is not ducted like the cruise airs
are.
Can't run the cruise air's while driving since they get their air
from underneath and don't fair well when road is hot.
Roof air cools front of bus fine.
Don't like using the roof air when parked if we want to use tv as to
noisy for my poor hearing. Start the front cruise air and can hear
fine.
For us, both have their uses.
