I have in depth knowledge of both the cat and cummins spent four years working on and specializing in EPA 07 and 10 emmisions . As a cat guy it really pains me to say this but stay away from SDP C15 engines. They are the nightmare everyone says they are. Cummins after treatment is designed much better my only suggestion is follow the maintanence schedule exactly if it says clean the dosing valve (you find out what that is) clean it. Says clean the catalyst and dpf clean it this will greatly reduce un expected down time . Try to idle very little . Turbo's egr valves coolers all that stuff will be a problem but all I can say is welcome to 2013 truck engines . The problem with the cummins IMO is that if you spec the engine for after treatment reliability fuel economy will suffer and vice versa. What I mean is if you keep the 07 isx working I.e. pyro temps up the dpf can regenerate without doing an actual regen. Also the harder you run it you stand a lesser chance of the variable turbo sticking and binding because it will be moving and doing its job. And light duty cycles can cause the egr cooler to soot up and plug. Now the best way to get economy we have learned is to keep boost and pyro low so you can see the confict
