This is by far the greatest and most comfortable truck ever made. And if power and performance are what you want then this is the truck for you. The only trouble I had was with the injectors and luckily they were covered by the LB7's extended 7year/200,000mile warranty. Other than that I have never had trouble with this truck. Plus the aftermarket for Duramax's is so wide open to your imagination.

I've pulled 3 horse trailers up hills to Lake Tahoe and it passes normal traffic. Very reliable. Not a great turning radius... requires 3 point turns many times but very reliable so it's worth it.

My overall experience has been great! The only problem that I have had in the last 2 1/2 years is the driver side mirror defroster died and had to be fixed. No major mechanical problems and I think it is a comfortable full size truck to drive.

Overall Good Truck. I am impressed with the sturdiness of the truck. The 6.0L has provided plenty of power with only occasionaly towing. However, the engine began knocking for the first 5 minutes on start up at about 17000 miles. GM says it's o.k. but extended the engine warranty to "make me feel better." Had to have work done on steering column as it began knocking when I hit bumps. Speaker in passenger door had to be replaced. I am now noticing some delay or slip in the transmission when the stop light turns green. A little scared where this all might lead. Don't have the Allison.
