2003 Tacoma V6 Extended Cab without 19' FC got about 18 straight Highway. I don't know what the gear ratio was. Pulling the 19' FC caused mileage to drop to 11.
2012 F150 5.0 Extended Cab without either trailer, straight Highway 24. With
25' FC I am getting 17 straight highway running about 60. About the same pulling the 19'.
My biggest issue was not really mileage as it is just an expense, my biggest issue was up and down the mountains which is every trip for us.
I use the F150 exclusively for a TV.
Wow, that performance from the 5-liter F150 is impressive. Do you know the rear axle ratio offhand? The only time my '07 5.4 liter w/3.55 lsd sees 24 mpg is coasting downhill!! I tow about 65 mph most of the time, and get 11ish towing. I knew the 6-speed would get better mileage, but that's crazy! I need to figure out how many miles it would take to justify the cost of a new truck.
