When I 1st saw that hybrid approach I thought it was rather strange because an ambulance are out of service for a while when they are at the hospital. Why Tie up a piece of apparatus with the associated manpower for something like this? The SUV as a medical response vehicle paired with an engine company (or truck company) at least to me makes a lot more sense that way the wear-and-tear and the large piece of apparatus is reduced and it is kept in service, although with less manning, while the if UV takes in the medical run.
