Right there with Buck50HD and SkiSmuggs.
60-62mpg and 10.5-11mpg all day long with cruise on.
Higher the speed = lower gas mileage. 30 mile per hour head or side wind will wreak havoc with the mileage too.

I get between 8-10 MPG's with my 05 screw 5.4 pulling my 30' TT depending on terrain.

Second trip out with new 5th wheel and '13 F150 twin turbo. ON a 220 mile round trip on 4 laners and back country roads in the Lancaster, PA area I got 11.9 mpg. Really satisfied with power and mpg.

You basically have the same setup as my old truck and trailer. My trailer was about 5700lbs loaded and i averaged between 9-9.5mpg towing

Towing around 3000lbs with my sled trailer (open but with a v nose salt shield) I hardly noticed much difference over a 150mile drive.
However, when towing my new pontoon boat the other day, even though it weighs less than 3000lbs, the wind resistance made a huge difference and I was down in the 8mpg region.

I think everyone should also state what year, bed length, engine, etc. It'll be a better survey.

I'll start

Millage: 37k miles
Engine: 5.4 Triton
Bed Length: 6.5'

Trailer: dump trailer 7k pounds
MPG: Over rolling hills, mix highway and city 8.5-10mpg

5.4L 5.5' bed
20" wheels with 3.55 gears
MPG- with mix driving i averaged 9-9.5mpg

Nice camper! How come the landscape is so green?

Rob28 nailed it. I'm seeing a trend, that big, flat tows in the pre-2009 models, depending on speed, are running in the 8-9 range, and you smug ECO and other new tech folks are seeing around 11+. My envy is large, but my monthly payment is low.

BTW, my original mileage was at 65-70 MPH. Probably a bad idea, based on this thread.

Year: 2007 Stock
Millage: 25k miles
Engine: 5.4 Triton
Bed Length: 6.5'
Cab: SCREW
Tire Size: No clue. Stock
Rim Size: No idea
Gears: No idea. How do you figure this stuff out?

I get between 12.5-13.5 pulling my 20 foot crownline boat. It just depends on the road. On the highway I was getting 16. I'm pretty happy with it.
