We have a heavy rescue with backboards, scoop, stokes basket, AED, splints, KED, c-collars, O2, full jump bag, suction, etc. The biggest difference between our BLS non-transport trucks & the Ambulances is the AED. Plain jane AED (as a nod to first responders) as opposed to a Lifepack 12 (soon to be 15's!). Our FD also just bought a F250 to use as a First Responder truck and this will probably have a Lifepack on it now that we have a couple of EMT-B's, a EMT-I and a Medic running more often than not.
