Our roof air's are horribly noisy, especially if I open the main vent (bypasses the ducting)
Generally at night, we'll run the front only and let the ducts feed air to the bedroom, then we don't have to hear it.
I've heard common basement a/c's used in class A's are obsolete and very hard to get parts and repairs for. Far as I know, Winniebago/Itasca was the only mainstream manufacturer to use them. (note I'm not talking buses here, just regular class A's)
I think even two million dollar Prevosts have roof air. Four or five of them.
