2014 245 RKS towing

I am getting a newer F150 to pull this travel trailer.
3.5 eco boost.

I see gear ratios of 3.55 and 3.73.
What would be the recommendation?

It all depends on trailer weight, towing capacity.... With limited info on the truck and camper it looks like you should be well within your towing specs, the 3.55 will save you on fuel cost. If you're towing at your limit, the 3.73 will give you a little more off the line grunt, less gas mileage

3.73 gives you more towing capacity.


Speaking from recent experience. If you decide to upgrade your trailer 2 years and 2 months later


You may want a bigger trailer. No one ever goes smaller second time.....haha


Good Luck.

Depends on the year. 6 speed, 3.73, 10 speed 3.55. If you plan to drive it more than just when towing, the 3.55 will be better overall since the 3.5 doesn't need to rev high like the 5.0 to hit the power band, which is what the shorter gears give you.



If you look at the Max Tow package Ford offers with the 3.5 EB, the ratio is 3.55 as that one works best for both MPG when empty and power when towing. I have an 18 with Max Tow. Pulls my Coleman around effortlessly and would not want the shorter gears since it is also my daily driver, and fuel economy is important as well. I get 20-22 MPG in it when driving to-from work every day.





With the 10 speed, the lower gears with the 3.31 rear end are equal or very close to the 6 speed with 3.73 gears. The 3.55 are better than the 3.73 with the 10 speed vs 6 speed. Also since the EB produces the torque way down low starting at 1500, the pairing works very well for that engine. If it were the 5.0 where the torque is near 3K before it pours it on, then 3.73 is a must since you want the engine to rev up that high quickly.



Hope that helps some. You also will find 3.55 much easier on the lots than 3.73.

3:55 is my choice!

I have a 2018 F150 with the towing package 3.5 EcoBoost and 3:55. It gives great hwy mileage and 9.5-11.5 mpg towing nearly 8200lbs. I am extremely happy with this setup. The 10 speed in tow/haul mode stays mainly in 7th gear at 2000rpm sometimes 8th on flat ground. I don’t think you will go wrong with 3:55!
