GMC Duramax 360HP w/6 speed Allison

The new Duramax engine is better than I hoped for. It has tremendous acceleration, quieter than ever and reminds one of a sports car. The 6 speed Allison has smoothed the shifting much better than the 5 speed Allison. Cruising at high speeds is unbelievable for a heavy duty truck. This is my third Duramax 4WD 2500HD and they keep getting better.

It's a love/hate relationship between me and this truck. I first fell in love with the outside design. The front view has the same appearance as the Denali. It rides high and has a very aggressive look. It has plenty of power and has yet to be challenged by any load have had. The 6.0L is one of my prized possessions. Most of the of the negative comments here should have been expected, I understand. It sucks gas. I'm averaging around 14 MPG. It offers a bumpy ride. The dash board seems cheaply made, with thin plastic. The rear end can get loose quickly on wet surfaces. The power steering box went out twice. 17 inch rims on a truck of this size is an injustice.

i love my pickup, hauls my 40HP massey with bucket and brush hog like it's not even there. with banks big hoss bundle it hauls balls and doesn't think twice. awesome truck wouldn't give anything for it. it's dependable, and with all the mods it catches eyes everywhere i go. as of now, until ford puts out the 6.7L would only recommend a duramax. cummins is good but everything around it is crap and rides like a semi. duramax is king right now. i just can't say how much i love my pickup.

Great Reliabilty Poor Interior

2006 GMC Sierra 2500HD SLE1 4dr Crew Cab 4WD LB (6.0L 8cyl 4A)

Better fuel mileage, reliability and smoother suspension than the comparable Ford. However, position of side view mirrors creates dangerous blind spots. Cup holders in front difficult to access. Front middle seat very uncomfortable. Front passenger seat lack of foot/leg room r/t air box, this lack of space is even worse when there are passengers in back seat and you have to move front seat forward to allow more space for them. Lack of leg space for back row and you have to turn your foot sideways to get in/out of vehicle due to the lack of space between the seat and exterior section of vehicle where door attaches. There's more. Overall this is NOT a vehicle for a crew. This is no CrewCab.

I have had several of the old classic 2500 4WDs and this one is by far the best truck I have ever owned. The styling is so much nicer than Chevy. Only one little problem with the transmission so far. All my previous GMCs spent a lot of time in the shop for warranty work, but not this one! Build quality seems so much better now.
