gmhdfan has a valid point. Probably 97% of diesel buyers never tow enough or keep their trucks long enough to justify all the added expense of maintaining them. Sure if you're going to consistantly drag around heavy loads and/or keep a truck for 250,000+ miles a diesel is tough to beat. How many really do this? very few i'd bet. My 97 454 burb had 200,000 on it when I sold it and it still didn't burn any oil and had the original tranny in it.
