I think they may have bought some more '08 E-Ones and put them in service in the downtown high incident companies. I saw Engine 2 on the news the other day and they were in a new E\-One that looks exactly like E10. I know 2 used to also have an ALF.
There are also some extremely minute differences between E10's E\-One and the similar rig posted on page 21 of this thread for E31. The turn signal, LED warning light, and side facing white light on E31 are bunched tightly together. They're spaced apart on E10. Perhaps the difference between an '07 and '08?
