I am really wanting to buy an 08 mega 4x4 with 6.7. I have been researching this for 2 months. I have never seen so many complaints and problems with any truck ever. I have never heard of so many customers trying to get the Lemon Law applied. If Dodge and Cummins really feel they have fixed there problems then instead of offering 2.99 per gallon fuel for 12000 miles a yr for 3 yrs they should in writing guarantee you that if you have CEL problems and your engine is not preforming to a certain standard they will buy it back. I really would like to get this truck and I am just terrified I will have the same problem with mpg plus all the engine problems. I also no that any resale is out if they do not fix these problems because everyone will know to stay away from this motor.
