2006 Chevrolet Silverado 2500HD LT3 6.6L turbo diesel from North America
Summary:
Best engine/transmission combo out there for moderate to heavy towing, Allison tranny is bombproof
Faults:
Nothing yet, truck is still relatively new.
General Comments:
Pulls like a freight train
Decent mileage for a truck that weighs over 7000lbs empty
17mpg in town / 19.5-20mpg highway
Allison 6 speed transmission and the technology that goes with it is incredible.
Would you buy another car from this manufacturer? Yes

Update Aug 8, 2012:
Around 95k on this truck now.
Do all general maintenance myself and used oil analysis (UOA's) about every 2nd-3rd oil change. Engine is in great shape and running strong.
Shocks replaced at about 85k or so, probably should have been a bit sooner as one rear was leaking oil.
Still very happy, and plan on driving til she drops dead. Hopefully will be 300K + or more is my goal.

Update Feb 2011:
Truck has approx 74k miles on it, and no major issues except for both front wheel/hub bearing assemblies had to be replaced in Nov 2010 at about 70k miles. One would think that an HD 3/4ton truck would not wear the hub bearings out that quickly, but from online forums/discussions, it does not appear to be all that unusual.
Truck developed a very strange vibration/hop in the front end at 55-60mph on various road surfaces. Ended up being the "slop" in the bearings. Of course they are "sealed" units with ABS speed sensors in them, so it's not a simple grease/repack. Not happy, and it set me back about a grand for parts and labor at my local mom/pop shop. Dealer wanted closer to $1300-1400.
Also, air bag front impact sensor went out this month and had to be replaced and the system "reset". Of course you cannot do that yourself, so an $85 part that I could buy from GMpartsdirect.com and plug/play myself to replace it, ends up costing nearly $350 by the time the shop can diagnose the problem, get the part, install the new part, and check/reset the system. I guess airbag and ABS, etc cannot be read/cleared by OBDII scan tool that any auto parts store will let you use.
All in all, very happy still. I do all fluids, filters, grease, etc. myself, and the truck has no issues except for the above.
