Okay, I am not going to going to argue cost v. use, but more of an environmental angle.
I applaud this company carrying MCI, HazMat, Incident Command equipment, etc, power to them. I am interested in how often they use this specialized equipment, as opposed to just a BLS medical calls. As someone indicated, this truck may carry heavy rescue equipment, extra SCBA tanks, or even a compressor. Does this equipment need to roll on medical calls. Do they need to pay for the fuel and maintenance to cart this stuff around town, if it isnt being used.
Wouldn't they be better off with a less sizable ambulance in addition to a SUV (with mobile command post, if they wish), and a set of trailers, that can be specialized. Maybe one for MCIs (Boards, blankets, etc,), another for HazMat, that can be deployed with the SUV? Let it all be pulled by the Chief SUVs, I dont care.
Am I making sense? Lower Fuel Costs+Specialized mobilization=cost savings, and the wealthy town can visit the new shiny trailers as often as they wish.
