My wife and I just completed a trip from a few miles North of Louisville, KY to Northern Alabama and back.
Truck: 2015 f150, 2.7L, 3.73 EL rear axle
Trailer: 6500lb. travel trailer
Total miles driven: 878
Miles driven towing trailer: 669
Average MPG while towing: 13.5 MPG, with a high of 14.1 and a low of 12.6
Regular 87 octane gasoline, mostly Interstate w/70MPH speed limit, rolling terrain with several long hills. Mostly used cruise control, no A/C, 2 passengers.
I have a Reese WDH with dual cam sway control. I started the trip with the hitch set per the instructions in the owner's manual at 25% FALR. Big mistake. The rig was all over the road, blown around by even the slightest cross wind, and pushed and pulled severely by every passing truck.
I changed the hitch adjustment to provide between 90 and 100% FALR, and the misbehavior went away. It behaved very will the rest of the trip, and was comfortable and pleasant to drive. IMO, if the WDH is properly adjusted, stiffening the rear suspension and adding E rated tires is unnecessary. YMMV
