Best vehicle I have owned.

I bought my 2004 GMC Sierra new, in 2004. I have driven/worked it for over 20 years now, probably doing some thing it was not designed to do, and over the course of 409,000+ miles it has performed better than expected. The Duramax LLY engine has given me excellent power and fantastic mileage, considering the loads I have pulled with the truck. The Allison transmission has held up under the workload as well. I have taken the truck into places I was told it would not go, and gotten back out every time. I consider it the BEST truck I have ever driven, or even ridden in over the past 20 years. I will maintain it and keep it the rest of my life.

Fantastic truck!

I bought my Sierra 2500HD 4x4 new in 2004. I have worked this truck(some would say overworked) for 344,000 miles with NO major component failures. I do take care of this truck with regular maintenance, using Rotella oil, and Lucas in every tankful of fuel. No injector issues, no problems with the Allison transmission, or any major components. I tow heavy loads, and drive some rough terrain. I do not treat is badly, and It gets me there and back, AND fits my butt. I have been offered good money and great trade deals for it. I will go for 500,000 miles.

Great truck

Truck has served me faithfully for around 10 years. Can't wait to get a new one. Highly recommend. Low maintenance. Let's me when fluids are low and oil change due. Handles well. Very comfortable to drive.

GMC HD2500

This has been the best vehicle I have owned. Used as a work truck for 15 years. Have been proactive with maintenance and it's paid off. Should easily get another 5 years or more out of it. Didn't need a brake job until 155,000 miles. Just had rear main seal, crankshaft seal, oil pan and oil cooler seal replaced (not unexpected considering I pull a cargo trailer loaded with tools in Florida's heat). Never kept anything this long.

Engine’s a 10; body not so much

My 2004 Sierra 2500 HD diesel is used to pull a 3 horse, gooseneck trailer. It pulls wonderfully. Highlights are the looks, ride (when towing) and the HVAC system (great in all seasons). Only weakness is the rust in the lower body panels. I see this in lots of GM trucks, more so than in Fords of similar age.

Rust

For a work truck I love everything. Comfortable for the long trips, and has the rugged power when I need it to pull something. My only complaint usually with all GM trucks is RUST. They have work so hard to make everything else right on these, but it is time to invest why the cab corners, rockers, and fender wells rust so bad. I hardly see one on the road with out it. With sticker tags 30K+ you need to figure it out.

2004 GMC Sierra Diesel

19.3 mpg for big truck is impressive. I have had only one unplanned repair (replace brake lines) in last 12 years With proper preventive maintenance this truck should provide reliable service for 10 more years. Physical appearance remains excellent. Great overall investment...I am the original owner.

Hard working long lasting truck

My GMC has towed a 32ft camper up and down mountains and all over the north east and I never even felt the truck towing anything, it was taking a country drive. I e had my truck going on 13 years and she still looks and runs like it was 5. Will always drive a GMC.
