Several years ago the bus company for whom I drive bought a new 34 passenger bus built on a Ford F550 chassis with the new Ford-built 6.7. They got rid of it after a year because it literally spent more time at the dealership for repairs on the engine, always computer and emission control problems, than it did in service. It was replaced with a Freightliner chassis bus with a 6.7 Cummins engine and the company still has the Freightliner/Cummins bus which has been free of issues after several years of use.
The main problem was the fact that the bus has to fast idle for extended periods of time and I'll bet that it's the same situation for the fire pumper. They were never able to get the programming to work right to allow extended fast idle. The software "tweaks" ended up making it blow black smoke as it was being driven, caused it to regen every 50 miles and get extremely poor fuel mileage.
The salesman that sold my RAM to me last year told me last month about a 2-year old Ford 6.7 that had just been traded in for a new RAM because the cab had been pulled 5 times and the owner was sick of the problems with the truck. This does, however, seem to be an exceptional situation and I think that most Ford 6.7 owners are quite happy with their pickups.

In 2012 I was on an ambulance committee. With the problems of the 6.0 and the 6.4 we didn't give the 6.7 a chance. We put a ram chassis under the ambulance. Of course few years later we realize the ford 6.7 would've been fine we are ok with switching to ram. It's done great. We will probably buy another ram soon.
You should see the problems we had with are attack pumper built on the F550 with the 6.7.
Which 6.7? Chris
