I have the 2nd generation LLY Duramax engine in mine and i love it. I had to replace the injectors when i bought it at 130,000 but other than that i have just been upgrading. The ride is great, the seats are comfortable, the fuel economy is good, 20-24 highway, 15-18 city, if i keep my foot out of it(hard to do with 400 HP and 600LbFt of torque on tap). I have not had any major breakdowns since owning it. The transmission did blow up at 143,000, but it was a freak electrical short that caused it to engage 2 gears at once(lots of chunks in the pan). It actually got me all the way back to the shop in limp mode which was about 25 miles, 10 of which on a logging road.

Truck has been overall a good unit. Windsheild leak when new at passenger floorboard and behind dash. Took 1 year for local dealer to finally fix. Climate Control slow to activate fan, really noticable on hot days, seems I have to press brake pedal to start blower (wierd). Trans will sometimes start in 2nd gear, then shift to 1st. Usual problems with intermiediate steering shaft (now on 2nd fix), driver's seat belt and armrest broke, pass side also (wrty fixes). Also having wierd problem during cold months with intermittent dash light and guages recycling, no fix yet. Orig brakes are still strong at 90k miles, tire wear good, body still tight and quiet, engine strong with no oil usage

Truck rides very rough. Truck's brakes are sluggish. Truck is 6 litre not great gas. Truck has had all kind of problems! If you have to stop fast you are in trouble. That's why this truck has been in 3 fender benders. Had to replace complete rear brakes and rear seals .

Review
This truck has been used mostly on the highway, carries dirt/mulch and recreational toys. And has done so for 62,000 miles without a single mechanical problem! It was originally purchased for towing a camper. Within 6 months of purchase, rising gas prices made driving this thirsty vehicle downright painful! With the cruise control set at 65 station to station on an interstate,13.7mpg. Disappointments? The ventialtion system. The AC is not cold nor dry enough to defog windows. And the radio is horrible! Did I mention fuel efficiency?

Review
The quality of this truck is questionable. Major issues include getting only 275 - 300 miles/tank of gas. Serious steering problems with absolutely no long-term fixes. This is a widespread issue which truly makes the truck a misery to drive! Rust at less than two years. Faulty air, seating, and other minor repairs. I can hardly imagine buying another due to GM's lack of being able to warrany their trucks and offering a fix on such a major steering issue. All they offer is a lube which needs to be applied every four to six months and does not really work well.

this is the fifth (sixth if you count
my Tahoe) gm truck that i have had and
it is by far the best. talk about
reliable. a heavy duty truck that has
no problems pullikng my triler in any
clime and place. in the snow, on the
beach, it does not matter. talk about
space, i have two kids and a dog and we
travel with no problems, even on long
trips. i will never own another type
of truck, from any dealer...now a
hummer...that is a different issue.

This truck is awesome. We pull a 5th
wheel camper and it pulls it like there
is nothing there at all. Great truck.

Absolutely the best truck I have ever
owned. During it's maiden break-in
run I got 23.8 mpg. When engine is
broken in mileage should be even
better. I drive between 55-65 mph and
this seems to be the "sweet spot" for
performance. Got it to haul our slide
in camper and this will be no problem
now. (Not like our 91 Silverado which
on it's best day with only one person
got 20 mpg)

I appreciate the diverse choices
when purchasing vehicles but choose to
pick GM d/t the ability to find
anything from fast sports cars,
Corvette, to tough Durmax Diesel. The
current Vehicle of choice is as
described above and I wouldnt tow w/out
the performance of the GMC Sierra 2500
HD Durmax Diesel. Not only does the
beautifully engineered design look
great driving down the highway but also
performs outstanding w/absolutely no
problems. This is my 3rd Duramax and
would recommend it to any serious
driver that needs a truck w/towing
capacity. Not to mention gas
milege...what truck of this capacity
can get
