I can understand the acceleration decrease, but the gearing should have been able to move your trailer with ease.
Not so. Additionally F550 would downshift on each freeway over pass.
I rented F550 w 6l when my F450 with 7.3l broke differential.
7.3l with manual was moving the trailer with no problem. I made topic about it on Truck forum and that was where I was informed about different engine tuning on heavy vehicles and possibly rentals.
Original impression when the truck with alleged 50% more HP is not moving the load like the old one was pretty bad.
