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.

I researched long and hard when deciding on the $$ for the Duramax/Allison combo. Man am I pleased! It pulls my travel trailer like it wasn't even there. MPG has been better than my previous Firebird. Comfort is much better than I expected for a 3/4 ton. Looks? Man, you can't beat the Fire Red color! Don't know what it might take to wipe this smile off my face!

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.
