95k1500 Posted May 19, 2009 Share Posted May 19, 2009 My fire department is getting ready to purchase a new fire truck. We have the choice of two engines, Detroit series 60 or the Cummunis ISM. All of our trucks minus one have the series 60. We have never had any issues with the engines. The salesman is telling us that the Cummins ISM, won't have the DPF stuff on it if we went that route, the Detroit would. What are your preferences, ideas, concerns, etc with these two engines? One better than the other?Any info would be helpful.ThanksDave Quote Link to comment https://www.bigmacktrucks.com/topic/9433-engine-choices/ Share on other sites More sharing options...
HK Trucking Posted May 19, 2009 Share Posted May 19, 2009 DPF's are a pain in the ass.You say this will be in a fire truck, so how's that gonna work when the DPF tells the ECM that it's time for a "parked re- gen cycle, and the truck is at a fire scene pumping water?
