The power is amazing with mine. I pull a 206 champion and it acts like there's nothing being towed. Now I wouldn't believe everybody on great gas mileage as my fx4 gets 10/11 towing and around 16 without.
I had one pulling a Z522 ranger, you never knew it was back their. I have never even had it gear down with the EcoBoost. I pulled a 50HP tractor with a bush hog on the back and a front end loader on the front. I pulled that tractor from Tyler to east of San Rayburn at speed limit and it never gear down with it either. I found my mileage to be about the same, 9/10 pulling a tractor or boat and 15.5 to 16.5 depending on speed.
