My buddies 2017 GMC Sierra Denali 2500HD (Duramax) gets 28 MPG cruising on the interstate at 67MPH. He drives a little slow because he is used to being in his monitored company service truck for most of his driving.Bigger trucks do not always get worse MPG and they're not always more expensive.
Makes me so mad. Giant ass 3/4 ton 4x4 truck sneaking in just under 30 and I'm celebrating if I can pull 18.5 at the same speed
Now, I don't have Duramax/Allison repair bills...
