Does anyone know of a dealer with a good service dept. in the northwest Iowa area. I live around the Storm Lake area, and I know if I needed any warranty work done on the new 6.7, the dealer in Storm Lake would not have a clue. Probably wouldn't even know that the 5.9 got replaced with the 6.7. I bought my truck at woodhouse in Blair, NE, but don't really want to drive all the way out thier for the AX flash. Let me know if anyone in my area has a good knowledgeable service dept.
