Have I been doing it wrong all these years?
I have been towing our 30ft fiver for years with a Silverado 2500 Duramax. Have been using the tow mode and get right around 12MPG. Today we headed out. I zeroed out the trip computer before leaving. ...

The tow mode does not have much effect when towing on flat roads at crusing speeds. It makes the engine rev more when starting from a stop (which uses a bit more fuel), and it causes the transmission to downshift when you apply the brakes on a downhill grade. But you knew that, of course.
On older Ford vehicles, "tow mode" disables the 4th speed, which has a big impact on fuel economy.
If you are towing on a flat road and the engine and trans temp stay in the "normal" range, don't bother with "tow mode". Be prepared to manual engage "tow mode" when you encounter any hills.
This worked for me for many years with my E150, admittedly towing a smaller trailer.
