Replaced older model

Newer, fancier, hard working vehicle. I use to tow trailer. Truck pulls easily. Don't even know I am pulling! Great truck. With trade in and special offers, I got a great deal.

Awesome truck

This vehicle is exactly what I have been looking for. I have a motorcycle that I will be buying a toy hauler to tow behind this fantastic truck. This vehicle is so comfortable I enjoy driving it.

Trailer Hauler

I have a 25 ft travel trailer that is was pulling a 2015 Siera 1500 but when on the inter state it was continuously down shifting.and the engine was running in the med 3500 RPM just to maintain 65 MPH . the 2500 Diesel pulled the same trailer on the same road but it never down shifted and cruised 68 mph and held rpm to around 1650 rpm's and that was even going against a 20 MPH head wind. Plus was able to get a little bit better full economy. Great Truck

This is a proper truck

I upgraded from a GMC Sierra 1500 to this GMC Sierra 2500HD Denali which is fitted with the Duramax Diesel 6.6 lt engine. It is a huge upgrade. The suspension is tough and much stiffer. The engine is smooth, starts easily (warm weather so far) and the fuel consumption seems quite good so far (1000km driven so far). Probably averaging about 12 lt per 100km so far through the break in period which will be heavier. Features I really like on this vehicle are the luxurious leather seats, the diesel exhaust braking system, the smooth gear changes and the crushing low revs.

Sierra Reveiw

Rea.lly nice truck. Has some rattles that I think should have been corrected before I took possession. Diesel engine has plenty of power and is very quiet. Rides really stiff but being a heavy duty I should expect it.

New purchase but so far love the truck

I shopped very hard before deciding on this vehicle. I believe GMC 2500 is the best looking in the space and provided exceptional value for price.
