hatman74 replied to Ke32's topic in 2015-2019 Silverado & Sierra HDYes I wish I was that guy! Lol I'm pretty picky. When I was going to lay out that kind of $$$$, I wanted to get it right! I drove the 6.2 eight speeds, 3 different times. Two were fine, one (Chevy) seemed liked it hesitated and kicked. They were new trucks, so I took that into consideration. I didn't like the aspect of the cylinder deactivation. I liked the power of the 6.2. My 2005 had,5.3 Flex, headers, tune, cold air intake, 3 inch exhaust, etc. I am going to leave this 2018, stock. GM has flowed the heads almost to the max, and I do like the quiet! Guess I'm getting older! Lol! I've kicked it down a couple times to pass on a two lane highway. It sounds like it has a cold air intake. I'll have to say, the transmission, shifts smoother than my wife's 2013 Terrain Denali AWD. This truck surprised me, I knew I was going to like it. I didn't know I would fall in love again! She's made to pull and please!
hatman74 replied to Ke32's topic in 2015-2019 Silverado & Sierra HDI've had 1994 GMC , 2000 Silverado LT, 2005 GMC SLT, all 1500's. the 2000 & 2005 were 4wd. I ordered a 2018 GMC Denali 2500HD CC z71 4x4, October 1, 20017. Got it in November. I went back and forth on a 1500 max trailer 6.2 and a 2500HD, for three years! I didn't want or need the diesel. I was hoping GM would make the 6.2 with a iron block. Didn't happen. So I read all I could find, about the 6.0. Pretty much bullet proof, if you service it. The ride around town, is a little stiffer, if you have to go on rough roads. The ride on the interstate, unbelievably smooth and quiet! (Also; my neck and lower back are fused!) The gas milage around town, not much different than the 5.3"s. Interstate at 68 - 70 mph, 13.7 - 14.6. Not what I was hoping for, but I already read it probably would be less than 15mpg. I have 8600 miles on it now. Would I do it again? ABSOLUTELY! I Love this truck! I will never go back to a half ton. Bigger and better brakes,frame,etc. The price difference between a 1500 and 2500HD, is really small. I'm not pulling anything right now but a 3500lb utility trailer. Loaded with 3 cubic yards of mulch, I can't hardly tell it's back there! Looking for a Sea Ray 280 Sundancer( 8500lb) now. I think if your willing, to give up a little ride comfort around town and know your milage, is not going to be great. You will be happy you got a 2500 HD. Good Luck! here's a pic. of mine.
I waited two years for GM, to go bigger than the 6.0. Did not want or need a DMax. I drove both. Liked the power of the DMax, but just didn't need it. I always thought GM was going to make a 6.2 Iron block. Got tired of waiting! So, in Sept 17, I ordered my 18 Denali 2500hd, 6.0. I absolutely Love it.
Have a 2018 GMC 2500hd Denali. Complete front bumper,lower chrome,headlights, chrome grill surround,24" back on hood, same on front fenders, A pillars,chrome on tow mirrors, roof from windshield to marker lights. $900 ,LLumar, 5 year warranty. I think it was worth it!
