2002 GMC Sierra 2500 consumer reviews

The truck is a tank. Ask it to pull something...no problem. The only downside is gas mileage 12 mpg if your lucky. If your towing a heavy load down to 6-8 mpg. But sometimes you need a Tanaka and mine has reliable. 215,000 miles on it now and I wouldn’t think twice about driving it cross country towing a 30’ toyhauler.

Very reliable tank of a truck. Has never failed on me and has continued to give perfect performance time and time again. Only wish I could have owned it sooner

I bought this vehicle for Towing, I have owned a few of the 8.1L GM trucks. They are becoming scarce because the last one produced was 2005. People mostly run diesels these days for towing, but for all around, less then 10K miles a year, big block gas is the way to go. Love the truck, its extended cab on 37" tires. Not a ton of options, but that is the way I like it, its a truck and does what I need it to do. You won't be disappointed if this is the type of vehicle you are looking for.

This truck gets the same gas mileage as my old 6.0 liter GMC 2500, but it's much smoother to drive. Both vehicles had the 4.1 rear axle, which I recommend for anyone pulling 7500 pounds or more on a regular basis with a gas motor. The Allison transmission on the 8.1 Liter is silky clean and it matches up so well with all that horse power. Our 6.0 was always a little underpowered when we pulled our living quarters horse trailer, this 8.1 really is much stronger. The result? Easy uphills, less wear, better gas mileage when towing. I loved the 6.0 for it's durability, the 8.1 is the same. This truck is GMC Trucks at its best, in my opinion.

Great Truck. I tow with this truck a lot and it has amazed me. I have the 6.0 300 hp, 4:10 rearend, long box extended cab. The only things that I have done to it in 10 years is a EGR valve and replaed the two front speakers. Love this truck.

Great truck, workhorse, tons of power and torque, can pull anything, very comfortable feel and ride, poor fuel mileage though

Great truck! Only con is MPG but with aftermarket intake and dual exhaust best MPG was 15.7 on highway. Great in snow even in 2WD but will spin tires easily. Will pull anything you put behind it. Tricked out with lots of crome and matching topper, gets lots of comments.

Only downside to this truck is the gas mileage... low teens. But it'll pull a small mountain if asked. Unbelieveable amount of power!
