Stock? Pfft!
It will interesting to see what a DPF delete does. These trucks are so much more efficient than the non-urea DPF trucks. As far as longevity, I think we are still going to have the same issues with EGRs/turbo and eventually the DPF. I am going to try to get 15-20K on mine before tuning it. I'm at 8k now and it only gets about 100 miles a week on it at the most so it will probably be a while.
