I'm a diesel machanic for the navy. I love diesel engines. I'm haveing such a hard time figureing out what truck to get. It will be used as a daily driver. So I don't need 2wd. i would like to keep the truck as simple and as many MPGs as possible. No 4wd makes it lighted and a better ride and no front drivetrain to worry about. I've driven Chevys all my life. The LB7 has injector problems. The LLY has overheating and injector harness problems. The Duramax needs injectors about every 100K miles. 3k on injectors every 100K is not a big seller. And they take 3 days to install. Buy what about a Cummins. Great engine, but i don't know about the rest of the truck. The Dodge's lift pump will go but the injectors seem to last far beyond 100k. I've heard things about the interior and parts haveing premature wear. And as i'm a fan of chevy but live the Cummis. Or i go all out practical and get a gas truck. Unleaded is 20 cents cheaper then diesel. I could drive 36,000 miles in a gas truck for the extra 5k i would spend just to get a diesel truck. If i have the money by the time my enlistment is up i really would like a diesel, but which one is the right truck? Any opinions and personal experiences would be helpfull.
