Thanks, Bill
Hey Bill, as i recall he had about 17' of taper to the BoatTail.
As for his mileage gains, i remembered he also slowed his speed down around 55 and traveled a lot of older state hwys and such so he could maintain the gains and stayed off of the interstates as much as possible.

Good luck with yours. You can also use the template here in the tools and get the degree of angle that best fits your vehicle...
