The ONLY thing that equation is going to tell you is the speed at which your truck is going when at 2000 rpm. Just drive down the road until you are at 2000 rpm in high gear, then (hocus pocus), look at the speedometer.
how will that help me for mpg then

Thats not the idea behind it.
Torque and gear settings are individual for each vehicle.
It's only hokus pokus for someone having no idea what running at highest torque means.
Guess where your truck is running most fuel efficient? Next to the redline?

Wrong again.
Max torque is NOT where your TRUCK is running at most efficient, It is where your ENGINE is running at most efficient. Huge difference. There is no magical speed where you get your best mpg. The faster you go, the worse your mpg. Engine efficiency CANNOT change this.
Best you can do is match rpm to the speed you plan to travel by selecting proper tire and gear... not vice versa. If you are only concerned with mpg, then you must slow down.
