It's not the roads miles and I drive my truck like a little old lady. Its the offroading I do on ranch roads for my job in the oil field that tears them up so quickly. That being said I typically put 30-35k miles a year on my rig. With the exception of the KO2's, its not the experience with the brands either. It's the price.
