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

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)

2003 Sierra with 8.1 liter 345 HP and Alison Auto. Plenty of power for towing. A little hestitant on take off when cold. 20,000 miles in 6 months and it runs like day 1. Fuel mileage is absolutely HORRENDOUS!!!! Towing an enclosed race car trailer x-country avg. mileage = 7.95. Driving enmpty no load at all avg. mileage = 12.98.

The experience of getting better gas milage with the 6.0 motor in the GMC as opposed to the 4.8 in my Chev, makes me wish I had bought the Chev with the 6.o instead of the 4.8. Factor in the added pulling power, makes it far better. I highly reccomend getting the 6.0 in either model truck.

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.
