Freind drives a 450 hydro service truck and he insists it is detuned and doesn't much care for it.
I am in the market for a cab/chassis with the PTO and tow capacity. The specs on Fords website show the same power output so am assuming different power curves, matted to different shift patters, and gearing will change how the truck will perform compared to my F350.
Haven't driven one yet for a true comparisson.
i know of one locally who lost a valve in his early production f550 service truck, no mods whatsoever.
