I have a 2012 F150 Supercrew with the 5.0, and a 24RKS Trailer Blazer. I'm 13500lbs when lashed up. My solo mileage is 16mpg to 22mpg depending on how much highway driving I do. Towing seems to be 9.5 regardless. I am going up the Coquihalla highway here in BC in July, will be interesting to see what happens to my mileage on that pull.
I thought I'd post an update. I towed my trailer up the Coquihalla to Kamloops, over the bypass to Kelowna and down the #3 Crowsnest to Manning Park. My first tank to Kamloops was 9.5mpg, the second tank was touring around Kamloops and towing the trailer to Kelowna was 12.5, and through the Crownest and back home was 9.3. I was doing 100kmph to 110kmph, and the truck pulled the really steep hills at 50 to 60kmph. A couple of the hills on the Crowsnest were 40kmph, I did have power left but we are in the middle of a heatwave and I wanted to be conservative so as not to damage the powertrain. All in all I am happy with how the truck did, and the mileage is pretty good when you consider the terrain I was in.
