Update...

Now with 4200 miles on my SRW, Sierra 3500 Denali HD Crew cab with the Duramax diesel engine and Allison trans, the MPG has increased to 17.9 and still haven't added any fuel conditoner. I have also installed a ARE LS II Tonneau cover same as on my previous '05.



Great truck though I do have one complaint and that is the color keyed front bumper(Denali only) has several chips already.

I'm considering painting the lower panels and wheel well mouldings silver after seeing this on a 2015 Dodge 1500 Ram...



Something about white and silver I like.

Need to have it photoshopped first to see if it works as good with my truck's more square wheel wells, smaller wheel well mouldings and white bumpers.

Good looking truck!

Thanks and congrats on your win.

maiden voyage with ~ 10,000 lbs. in tow, got 9MPG at 75MPH through the hills of pa.

What rear gear are you using for that weight?

3.73 and it's part of the Duramax Plus Package.

Thank you....

a few photos of the Duramax Diesel taken at the NYC Auto Show last week...

Update, now with 64,000 miles, still running on the original Goodyear Wrangler SR-A LT265/70R18 tires, stopping with the original brakes and everything still works. Only rountine maintenance performed to date and tows a 32' steel trailer weighing north of 10,000 lbs., effortlessly, loaded with my dragster, golf cart and scooter as if it wasn't back there. Great truck so far!

What is the RPM @ 70 mph?

don't know for certain, around 2000. Besides, it's rare I'm doing less than 75 mph on the highway.

I have had acouple come thru my shop for routine maintanice and all the owners really have nothing but good things to say about those trucks

Wow... ED really 60,000 miles in 18 months , better sell it soon.

Wow Ed, I was getting salty about having 35000 on my 2500 Denali Duramax i bought last April. 64000 you aren't letting any grass grow under that baby.

I don't buy vehicles to sit in my garage collecting dust. It's transportation, it gets driven every day, 7 days a week and over 3,000 miles a month. That's how you log 64,000 miles in 18 months.

Well one thing is for sure , you get a lot of seat time... This truck must be your office too, you must spend 70 hours more or less in the truck every month....

2004 duramax.............225000 miles
other than routine maintenance (brakes, tires, oil change).....i finally had to put ball joints on it.

12 mpg towing...18.7 city driving

great truck

my 2005 2500HD Duramax was a money pit after 100,000 miles.

What were the biggest issues with it?
