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!!)
