It’s beautiful to look at but is nowhere near “Professional Grade”. This is a 3500hd which should be able to carry loads, it didn’t last a year. The engine is broke and has been in the shop for 3months.


I have had to of these before and I drive the xxxx

Just what I was looking for and the price was right. The color was the same as the truck I traded in. We have purchased a bumper pull camper and now mountain passes will feel like flat roads!!


Capable truck with the right options

Drove well and plenty of power, the SLT is perfect for us with the 40-20-40 front seat and without the extras that we don't need that are on the Denali.


Big Step Up

This is my first HEAVY DUTY truck and my first diesel. I have only had it a week and 3 days but it has already been on the job and been driven 1500 miles. I expected a much rougher ride than the Chevrolet 1/2 ton it replaced but must say I am pleasantly surprised. I compared ride quality to it's main HD competitors and this GMC 3500HD surpasses them. It has far more tech features than should be expected in a base model but I can appreciate the convenience especially for business. I love that it will project driving maps and directions from my iPhone onto its larger screen. I have not yet towed or seriously taxed its payload but the Duramax diesel is something to behold. Averaging 17.9 mpg over 1500 miles. The DEF fill could be a bit more convenient but putting it under the hood does keep DEF away from fuel filling and is not required often enough to be an issue.


Unbelievable towing capacity.

The Denali version is absolutely what we was looking for. Towing capacity is awesome. Has plenty of room in back for kids or cargo. Would recommend this vehicle for anyone who tows trailers. Duramax is what they say it is with Allison transmission best vehicle on the market.


New Truck

Good so far, we shall see what the future brings. Only had the truck for a week so far. I has been really good !


Great Truck. Very Quiet.

We are very Happy! We are very Happy! We are very Happy! We are very Happy! We are very Happy! We are very Happy!
