[Fulltiming]

Toward the end of the 2003 model year, Newell made at least 4 and possibly as many as 8 coaches with roof airs and the remainder with basement airs. #668 a 2003, may be the earliest in the switch from basement airs back to roof airs. #669 had basement airs. I am not sure about #670. #671, the first Newell with the ZF suspension built as a 2004 model during the 2003 build run, had roof airs. #672, 674 and 676 had roof airs but I'm not sure about #673, 677 or 678, which was the last 2003. So as is typically, Newell did not change from basement airs to roof airs at a model year change.

Bill is correct that 2004 Newells and those built since 2004 should have ducted roof air.
