That's alright saddlesore,
many time my older eyes and my typing fails me. Also when I use my cell phone it changes the dang words on me.
Ole yea, how do you like your 2019 Chevy with the Duramax? I have a 2006, 2500HD, 4x4, Duramax with about 90,000 miles on it, it has been a hoss. Your truck has way more power than my 2006, I can imagine that it pulls like a freight train.
So far I love it. I only have 7000 miles on it. During hunting season, truck, camper, trailer w/mules &gears runs about 16,500 #'s. It climbs Loveland, Vail, Monarch passes without even grunting. I hauled some gravel with a14 ft dump trailer and scales showed 19,300. It's gross specs is 23,000. My old 98 Dodge Cummins was 17,000. I get 21mpg hwy,about 18 in town and anywhere from 12.5-13 towing the full load.
I am not surprised one bit about your truck performance, the engine and transmission, drivetrain and gearing is one key to success, I believe. Dodge, Ford and the others can brag about horsepower and torque all they want, if you they can't efficiently put the power to the ground then their just loosing out. The most power does not mean its going to pull a steep grade any better, you know that of course I don't have to tell you, your an experienced pick up driver.
The best fuel mileage I ever got with my 2006, 2500HD, Crew cab, 4x4, Duramax/Allison (6 Speed) was 22.8 MPG on flat ground, never been able to duplicate that again, got close to 21 MPG. Driving the interstate on flat ground at about 70 MPH I get some where around 19.8 MPG. One good thing about my 2006 Chevy is, it does not have a particle filter or DEF, I like that part of it. My truck has a camper shell on it and usually I have about 200 pounds of tools in the back. My hunting camper is 21 foot and weighs about 4000 pounds or so, going to deer camp I usually get 13 to 14 MPG, according to the wind. Coming back from deer camp, more up hill grades it is usually from 12 to 13 MPG. 4000 pounds is nothing as far as towing, I assume its the tall height of the camper and wind resistance that's killing my towing mileage. Here around the house in the mountains, I can't get much better than 14.5 MPG, empty.
I would love to have a new full sized truck, not sure if I will go back to a diesel, no more towing than I am doing now. I tow a trailer and farm tractor now and then but mainly the 21 foot camper and that's not often.
Enjoy your truck saddlesore and keep us posted on its performance.
