I’ve been towing my 8000# (scale weight) trailer since 2013 with my HDPP F150 Eco. Payload is 2560#. Many many miles in the mountain west and I have never had an issue with engine braking being insufficient. I down shift early keeping RPM in the 4000 range and have never experienced beyond moderate use of the service brakes.
Now mileage, it sucks. At 60 MPH it’s 8 to 9 calculated because the lieometer is always 1 to 1 1/2 higher. LOL Bare mixed mileage rarely exceeds 14. I think the combination of LT tires and 3.73 diff kills it.
I don't think that the LT tires are the problem but the tread might be. I get much better mileage with my LT all-terrain tires than what you are reporting and I don't think that the 3.55 gear ratio is that much different either. In stop and go it does about as well as I expect a 5,600lb vehicle to do, which is in the lower teens when empty.
