Completed two MAJOR trips this year with my 2011 Ecoboost towing my 29QBH. I have absolutely no complaints.
I am Active Duty Military and in July I towed from Fort Lewis WA to Ostego Lake State Park, MI and back via Highway 2 almost all the way. I stopped by a CAT certified weigh station and combined vehicle and trailer weight was right around 15000 lb.
We now have just completed a PCS move to Fort Campbell, KY, currently living in the camper until we can move into a house. Again the truck performed admirably and without weighing again I knew we had more stuff as we had to pack for a medium stay.
MPG here was very dependent on speed and headwinds. Magic number is 60-65 mph. Doing this I would average around 9.5 - 10 mpg. In NE we hit major headwinds and the mileage dropped to the low 7's.
On the trip to MI and back average was around 9.3.
I love my Ecoboost and stand behind it!
