I have used it on a couple road trips though. It has gotten a best of 20 mpg highway, and gets 15-16 mpg in town. Towing a fully loaded 28ft enclosed gets about 11-12 at 70-ish mph and pulling the open flat bed with a car on it at the same speeds gets about 14 mpg.

I was just looking at a brand new 2022 at the dealer a couple weeks ago. Crew cab 4x4 with an $85k sticker on it. I would have expected they would do better than my 05, but the sticker has me keeping mine.

Mine's an '04 2500HD CC SWB, and I've seen as high as 26 mpg on flat ground at speed; normally more like 21-22 unladen. Gets around 13 - 15 mpg pulling the trailer, depending on the terrain, which is with about 7500 of enclosed Haulmark trailer with the car inside.

It's approaching 300k miles and smokes a bit, but the POWER!! I pass a lot of Dodge Rams going up hill.

Is my truck really 18 years old now?

(Ack!!)

Time flies doesn't it? Hard to believe these trucks are getting that old already.

I probably should have mentioned I keep mine on the hot street tune where it's gotten 20 highway. I could probably move it to the tame tune and squeak more but never tried.
Towing I use a tow tune that pumps up the power a tad but still easy on the trans.
And yeah, the pulling power going up the mountains is hilarious. Just use cruise control and it never slows down or even downshifts. Puts my old 79 1 ton with a 454 to shame. That's the sole reason I bought the darn thing.

I was hesitant to comment on the thread, because of the age of my truck.

Don't feel bad. I bought a brand new Harley a few years ago and it turned 22 on June 5th...
I bought my Silverado at 4 yrs old a couple yrs ago and it's now 11 yrs old. How the heck does this happen ???
