It has been a very good driving experience.

I like the towing power of my 2500 Denali diesel for the use on my farm. It perform on the farm and on the highway.

Great truck

Great driving truck, great looking truck and great nicely appointed tech and style inside and out. I have not towed anything yet but I am sure it will tow very well.

Man, what a truck!

I went from 2002 Chevy Avalanche (great truck) to my 2018 GMC Sierra Denali HD (2500 HD) Duramax. What a significant upgrade from 02. Only 3,500 miles so far, but xxxx, do I like my new truck. Best mileage on highway so far is 25.8 mpg with average hw mileage of around 20 mpg. The interior is simply superb, loaded with features, everything logically laid out, and super quiet (engine and road noise barely noticeable). Sound system and navigation (Bose Infortainment) are excellent. The ride is definitely stiffer, but not bad at all. But remember, this bad-boy is designed to haul a lot of weight. There are a lot of smart storage compartments throughout (not gimmicky or cheap) but the space under the rear-seats is very good (I added a cocoa storage organizer bin). So far I am loving my new truck. Denali plus offload options gave me all the luxury features I could ever ask for, as well as the sunroof, auto rear window, and factory bed liner. It was most expensive in its line, but I always keep my cars for 15+ years, so why not (I saved up for it).

Best vehicle I've ever owned. This is my 1st diese

This truck has surprised me. Milage is unbelievable. I'm getting 23 mpg dry. I bought it to pull my travel trailer. My old truck went into passing gear going uphill. My new diesel stay at 1500 rpm uphill or down hill never misses a beat. I am impressed. It is a beast. I highly recommend the GMC 2500 HD.

Great truck with excellent power

Truck is great but needs some updates such as push button start/stop and door sensors for locking/unlocking the truck. Overall, great truck with great towing capabilities.

Went all in...

Figured I?d go all in on this one...it is worth it. I love everything about it! Comfort, styling and power all top of the line. It is a 2018 GMC 2500 Duramax crew cab Denali 4x4 with leveling kit and 35?s. Best ride I?ve owned to date, great on road and off.

Great truck

I got this truck new and love it. It?s a great size truck and very roomy inside. Plenty of room for everyone in the crew cab. It doesn?t get great gas mileage, only 10.5 mpg right now but it pulls like there?s no tomorrow.
