I was hunting for the right 06.5-07.5 Duramax forever. I didn't like the 3/4 door size on Dodge crew cabs and couldn't trust a Ford diesel after the 6.0, 6.4 debacles. Most of the ones I was seeing were in the high $20's and had 200k miles. I thought it was a misprint when I found mine.
I researched the hell out of the Duramax and knew that the 0.7-10 were horrible mpg due to the new emission stuff, but the latest gen seems to be the best for HP/tq and still gets decent mpg for being able to tow 20k when needed. I was in Clear creek when I got a "service emission system" " speed will be limited to 65 mph in 803 miles. By the time I was back in Douglas county it said 60 miles until 65 mph limit. I added DEF fluid and cleared the code with an ancient code reader and it's been fine ever since.
After it's 2nd warranty is up, I'll look into tuners and deletes.
