When I started in the fire service a 69 ALF w/6-71 DET, W/5x2 trans, air brakes was almost new.That engine is about 2/3 the size smaller than the new rigs of today.and it did the same work that we do today. I know I am not riding outside any more,A/C is great for the summer.but when you need to get to the hosebed or even the mattedales you need a step ladder, or in to a tight driveway you need to park outside(I know leave room for the truck),But why do we think bigger is better. Maybe we should rethink our outlook of overloading our rigs to do to much and simplfied. I know I am old school but not all changes are for the common good. P.S. One of the spares was 61 Seagrave v12 Cont.gas ,vac/juice brakes could go like hell but sure didn't want to stop
