Impressive... Next would like to see if there's been a fuel economy improvement.

Now you are being funny. More power,towing and better economy do not go together.

Speed costs money.
How fast do you want to go?

Pulling the same trailer at the same speeds on similar routes...you sure can see better efficiency.

You are presuming that if you buy a more powerful truck, you will go faster. Go faster with the old less powerful motor and you will see a drop in efficiency.

Pretty much no one tows with their foot to the floor running at absolute max output, so it's silly to assume people would suddenly do so.
