Great performance

Vehicle: 2002 GMC Sierra 2500HD

I just recently purchased a 2002 GMC 2500hd Duramax diesel. It is a very dependable truck. It will pull any trailer that I need it to pull and if it doesn’t, a power chip can always be added for increase in horsepower and torque. This year and newer comes with the either a 6-speed or the automatic Allison transmission, both are great for pulling or just for driving, depending on what the owner mainly does with it. Without a chip this truck can get up to 18mph which is pretty good for a ¾ ton truck. Along with performing good this truck is also roomy with either the extended cab 4 door or the full 4 door versions. Another good thing about a diesel is that if they are taken care of they can ru

I love it! Wouldn't drive anything else. Purchased in 2002 - now it's 2008 and I wouldn't trade it for another! This pick up has never given me trouble, not even a flat tire. Perfect pick up! I love to drive it

I really love this truck. I call it "big truck". I don't like the gas mileage, aprox 13 mpg but what could I expect. It definilety has the pulling power, and the acceleration that I would want. I drove a couple of F-250's and I just didn't like the ride quality as much as I do this truck. I'm very happy with this truck




Great truck

I work in the oil patch in northern Alberta and this truck really works well here! I have the 8.1 liter gas pig but I don't care about fuel economy because it is so fun to drive! I have no problem keeping up to diesel's and some times pass them on big hills. I love the design, the ride is great and it really rips when you want it too. I tow a 10,000 flare stack regularily and this truck doesn't back down at all.




Very tough truck

Vehicle: 2002 GMC Sierra 2500HD

My truck is a bare-bones model set up for hard work--manual trans and 4WD, no carpet, plow mount, etc--and it's main use is hauling firewood. It's often driven off road into the forest on extremely rough ground, then out again fully loaded with green oak. I've got to be at the 9200lb GVW, but the truck still performs very well. The granny gear gets the load moving with no problem, and the dual-piston calipers stop her just fine. On the road and unloaded, the truck rides very nicely for a vehicle with so much load- handling capacity. All-in-all, I've been very impressed.

We enjoy our 2500K HD Diesel powered truck except the cloth seats (front) are not comfortable on long runs. We are of average weight and find ourselves having to stop frequently. The seat become flat and loose cushion after being seated for short lengths of time. Order leather bucket if you can.
