do you have stock wheels and tires?

I just took ownership on a used 2011 F150 FX with Max Tow(3.73) with 19,500 miles. Bought from Ford Dealer. Before driving off the lot I reset the MPG trip as I was on a full tank. I Drove it home 205 miles (hwy). I purposely drove very conservatively with coasting and acceleration to maximize real time mpg reading. I maintained speeds 55-60 mph , using cruise control as much as possible. The result when I arrived home left me with a heavy pit in my stomach and buyers remorse. I barely managed 15 mpg - This is all hwy miles and driving like a 85 year old granny. When I got home I found out how to check the mpg history on the car computer and overall I see that its showing an average in the 13 mpg range. I've spent hours researching this forum and reading most posts by others receiving 20-22 mpg which helped lead me to my purchase decision. I absolutely love the truck and how it drives and bought it only after extensive research and test driving other trucks. I am looking for the best advice on how to proceed with improving this situation. Please save any "it's a problem with your right foot" comment - trust me you'd be preaching to the choir as I'm miser. Did I just happen to get a bad one or can it be brought up to 15/22 like most everyone else on this forum?
I'm currently considering calling my local ford shop and checking on the following (gleaned from this forum):
1)transmission sensor recall
2)Power control Module (PCM) update related to poor fuel economy/emissions.– Need to be reflashed with the newest tune?
3)Fuel mileage TSB (Technical Service Bulletin)
4) Pull the plugs and regap them
5) Powertrain Reprogram?? Field Service Action # 13E03??
Bottom line I can't keep this vehicle at 12/15 mpg. Any other thoughts or help out there?
Did you rest the mpg before trip?
Everyone talks about poor mileage, specially during the winter months. My truck does not have this problem with the Mods I have. I did a test this week, since I average around 14-15 mpg around town, during the week is all highway miles (35 miles each way). I started the week at 14 mpg. . Today I am at 17.5 MPG avg 70 MPH. My mileage has not changed, and I'm sure if I drove 200 miles, I would get 19-20 MPH . When I first purchased the truck, I expected to get better mileage around town, but in reality, this Ecobeast does very well for a 3 ton 4x4 truck, better than my Escalade 6.2!!!

Cold weather can cause the mileage to go down due to warm up time and cold greases and fluids. A couple of weeks ago my 2013 Lariat 4x4 Super Crew was getting about 17 to 18 mpg several days later the temperature dropped to the mid teens and my mileage dropped to 14.5 to 15 indicated, this was on the same tank of fuel. I reset the mileage readout during a 150 mile trip (1 way) and it still read around 15. That afternoon on my way home the temperature warmed back up to near 50 and the indicated mileage returned to near 18 (actual mpg on my truck is more like 116.5 or 17 when compared to the computer readout). I do NOT depend on my computer readout to be accurate as far as mpg readings go. I rely on hand calculated numbers only for figuring average fuel mileage. A pretty real world mpg number for these 2013 Ecos is in my signature. If you have a 4x4 and are getting 20+ mpg average you probably live in Colorado and smoke lots of pot cause it ain't happening. Please don't try to BS me and say well my i instrument panel computer says this or that cause I ain't buying it.

I have 3:73 gears max tow. Crew cab & 6.5' box. It's a big truck. People that get better fuel economy probably have lower gears. No 4x4. & extended cab with short box. In the summer.

Mine is very sensitive to wind and temperature. On a 60 degree day with no wind I get about 18 mpg on the highway. The same temp with a tailwind it can go up to 22 and with a headwind down to 16. On a 20 degree day and with a headwind I get around 13.5-14.
