Tom is correct. Coaches #671, 681, 685, and 697 and higher had steerable tag axles. No coach prior to the 2004 model year had the steerable tag axle (ZF suspension) and 15 of the 38 model year 2004's did not have steerable tags. The steerable tag axle was part of the change over to a completely new suspension by ZF for tag, drive and front axles. So the entire suspension was changed.
The change over from HWH hydraulic slides to Valid electric slides occurred during the 2003 model year. #645, then #650 on had the Valid slides.
The next change was the major body style change in 2005 from the 2000 to the 2000i beginning with coach #722.
