Take a look at "lightly used" commercial trucks. For the same price or probably better, you'll get a LOT more truck with less crap and "technology".
While you are correct, I’ve had a truck with 19.5’s and the 450 is a good compromise.
And I don’t need to get a class B for a commercial truck.
If it was a tow rig, you are 100% on it. But my truck will be part of the farm, tow rig and family truck.
