Having owned an 07 6.7 Ram (first year of 6.7) I loved the engine and 6 spd auto transmission, but grew very frustrated by first year beta emission problems (DEF, 3 turbos, EGR cooler, nagging CEL’s), so I very reluctantly traded it off at 133k for a new 16 with DEF...Though it seems that Ram now has the emissions equip problems fairly well sorted out (thanks mostly to DEF chemical treatment), and the truck has amazing power (silly power), I’m beginning to think now (at 33k mi) about pre-emptively trading it off just before the100k warranty expires...Non-warranty emissions work can literally put one into the poor house...With a 5,000 lb camper (wet) and regularly climbing the Sierra’s, I seriously doubt the power or longevity of a gasser... Only time will tell...JMHO
