Well I returned from a 700 mile trip to western Montana and back, first trip with the truck. A few observations, it did not want to pass any tanker that smelled of diesel. Is this normal?Might have some thing to do with the 12. 6 MPG that the truck got. The truck was carrying a 10. 5 foot Bigfoot camper. Power was ridiculous, never slower of shifted on any hill. How do you tell if it does a regeneration cycle? Does it show on the overhead display? If it shows on the overhead then it did not do a cycle for the whole trip. All in all a comfortable truck with gobs of power, just wish it did not like tanker trucks so much.
