06' LBZ Duramax is a gem. Finest of the bunch in my opinion. If I were to buy a used chevy, that would be it.
They just did everything right. Calibration was solid. Six speed, didn't sound like someone dumped marbles into the cylinders and left them there like The LLYs were.
The 07' LMM I was around was a joke though. Had the low hpcr fuel issue. What a damn nightmare that was.
The 7.3 was awesome as well. They had a few issues. You needed to carry a spare glow plug relay (could use a screw driver in a pintch) and also a cam sensor. That was a very common failure.
The transmissions were junk for the most part. Not hard to fix. High pressue oil system had some gremlins there too. Valve cover harness was an issue.
Over all though, they were fairly solid. Biggest problems were glow plugs, good batteries, and good starters. They were the king until the 6.oh no came out. That was a real racket. Back then we didn't have these good camera phone's, but I'll never forget seeing 10 brand new 04 and 05s with the cabs off...... If they hadn't screwed up so bad, non of the other brands would have the hold they do now.
Tell you this, if you have a 97' powerstroke, and it shuts off every time you turn left, and doesn't leave codes, I'll save you about 3 grand and 50 hours of diagnostic time. The Injector Driver Module is full of water..... Oh eff me that was a nightmare. Funny now. But May 2005 was a very very dark time full of anguish and wanting to lay down in the middle of the road......lol...
I had similar experience.. my left bank of cylinders would shut off at random. Bought a new module, same deal... turned out to be a short in the valve cover gasket (which contains the control wiring). It would always test fine, but fail randomly..Tell you this, if you have a 97' powerstroke, and it shuts off every time you turn left, and doesn't leave codes, I'll save you about 3 grand and 50 hours of diagnostic time.

All of this thread makes me happy that I currently have no need for a diesel powered pickup truck. I'll stick with my paid for 2007 Tundra and the relatively simple gas motor.
I deal with diesel motive power at work, but won't bore you guys with my observations of medium speed diesels and their foibles. Realistically for what they get put through, locomotive diesel engines are insanely robust.
While I wouldn't call a 1 ton "heavy duty" I do like the new Chevs and Fords alot. I've always been a Ford guy, but these new silverado 2500s look good! Especially the Z71 all colormatched ones..
How cute... my cummins ram can tow your Tundra and get the same fuel mileage as yours does driving! :-)
I'd be all over a Toyota Hi-Lux quad cab if they imported one like they sell elsewhere. Tacomas and Tundras may be nice car alternatives, but won't come anywhere close to meeting my needs. Tundras especially, stupid high bed height, especially the side walls & tailgate. Yet less ground clearance than a ram. IE: it was not high due to some function increase, it was just styling. This tells me they never intended the truck to be used as a truck.
Older Tacomas were nice usable trucks, but still sucked at fuel mileage. But at least they were reasonable in cost.
