Vehicle: 2004 GMC Sierra 2500HD

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?

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 am pleased with my purchase at this time. It tows as is expected for a truck with its power- it is capable in the woods and farm as well as on the highway-- though the fuel economy is a jolt. But then again it is alot of weight to move.

Bought Brand New 3 months ago and now have just under 10K miles. The Duramax is all that and more. Excellent Truck!! Not one problem so far!! Ride Quality is awesome for a 2500HD Truck!

Vehicle: 2004 GMC Sierra 2500HD

During the first 3 months my truck was in the shop 6 times. Radio would not return CD, without it for 3 days. Once for extending camper mirrors, passenger side motor bad. Once for A/C, recall part not replaced prior to purchase. Three times for 4 WD, computer chip keeps going out and shifting into 4WD low on its own regardless of speed. I'll go back to the Ford F-250 with the V-10. More power, better gas mileage and reliability.
