Yes I down loaded it a while ago good motor specs but it relates to the stationary fire pumps for facility's like a tank farm we have 3 of them at work.

I wonder how much difference this spec (fire engine) has vs. what's installed in our trucks, especially since this spec sheet is dated 1997, and most of m939a2 truck engines are from late 80's to early 90's. Also was curious to see they list fuel burn of roughly 13 gph. That would mean at steady 55 mph, you're only getting around 4 mpg. I think most feedback I've seen recounting long trips claim fuel economy was 8 to 10 mpg.

Because it is industrial and a fire pump. Automotive, Industrial, Construction and Marine are all different animals. If someone posts an engine s/n, I can find the spec sheet

The ones I have seen are for fixed facility fire protection so if a sprinkler head goes off in say an aircraft hanger the 8.3 would power up automatically and pump water thru piping .
We have 4 pumps set up like this where I work when it turns on to supply water I've never looked at the rpms but they run pretty close to wide open supplying over 1200 gallons a minute. I will have to see what rpms they run at when tripped. I have also seen some newer 8.3 Cummins in actual fire apparatus I will attempt to get pics of both Wednesday when I return to work.

Not correct, because the truck traveling at 55mph is not requiring all of the engine's power to do so.
