20827 20829 20830 20831 are now in service out of Big Tree. 20828 hasn't yet been spotted.
9528, 9530,9531,9533 are now tracking on Fairview's routes. Along with 9502 9503 9504 9505 9506. Looks like just 9536 is the lonewolf at Hilton.
Also I've created this app, https://www.philadelphiatransitvehicles.info/NJT/NJT_selector.html to track the final days of the Neoplans & MCIs among other NJT buses.
