My local VFD just accepted delivery of their new $970K Pierce heavy rescue. Parked alongside their kinda-tired 199x heavy rescue (which goes out on virtually every call, per my app), I had an easy compare-and-contrast when my FF neighbor gave me the 50 cent tour. He showed me the new equipment that was also purchased for fitting to the new rig. It's a sea change in technology, and to my [layman] eyes, it seems as exciting as the company members claim it is. Gone, for example, are the heavy hydraulics. It's all cordless electric now. "E-draulics". Slide your empty air tank in the appropriate slot, outside, and the designee in the interior jump seat will open the door, spin the lazy susan tank rack as needed, and perform an expedient refill. And so on.
