Looking at either of these trucks in the crew cab 4 X 4 with the V- 6 options. I won`t be using it like a truck I have a Duramax for that it will just be transportation. I would like to know if any of you have one and how reliable they are once they get past the 75 -100,000 mile range. I`m hoping to be able to pass it down to my daughter in 3 -4 years but if they don`t hold up I may need to look at other options. These have been out for enough years now surely someone has put a bunch of miles on one.
