This from Martin Now:
While looking for a new work truck, I came across the Ford Cutaways/upfit side of their website. Shown here is the Transit Cutaway under ambulance.
While here is a photo of an actual type 3 ambulance.
It will be interesting to see if departments and companies bought the transit chassis more than the E-Series. Would this finally discontinue the remainder of what the E-series came to be?
