Between myself and my family, we have owned over 10 Chevy full size 4x4 trucks over the last 15 years. These have been for hunting, regular drivers and ranch/farm work. I have been reading this thread, trying to think of any unscheduled maint. or repair that we have had in well over 500k of mileage on those various Chevys and I am not coming up with any. The trucks had anywhere from 40k to 140k when they were traded. For me, you can't argue with that track record. I am sure there are good trucks made by the other makers. I have a friend with a F-150 with 180k and no major problems, for example.
