Well If I had drove home the last 2-3 times I would have easily hit 100k in a year but the drive from Texas to Idaho pretty much sucks.... So it took me 15 months to hit 100k lol. Only thing the truck has been in the shop for is a cam shaft position sensor which went out within the first 5000 miles. Ive changed my own oil every 10-15k along with fuel filters. I always use dell 400 and Napa Gold filters. I need to adjust my valves and do a valve lash but the truck runs good. I had all the fluids drained (tranny, diff, etc...) at 70k and all tranny filters replaced. I really like these newer 6.7's or atleast this one LOL. Hopefully this doesn't bite me in the ass as I knock on wood but maybe well hit 200k and zero issues.
