First GMC in 20 years and truck is a 2012 3500hd Duramax. Cognito leveling ith nothing i the box it will get what you have stated. With sled deck and 285/60-20 duratracs it has dropped to 18.
29000 KMS and the only real complaint i have is the god dam brake calipers rattling on rough road. I guess it is a GMC,Chev thing.
Nice motor and trans and don't mind the erea as no smell. Havent seen any cold weather yet but will see.
Been a Ford guy for years and didn't even look at the new 6.7 for other reasons over the years. Maybe in a couple years.
One more thing the best way that you get fuel mileage is to lie about it. lol
A heavy one ton truck is not going to get 28 miles to the gallon unless it is a 2 wheel drive regular cab with no weight.
