I anticipated once broken in 16.5/17.0 city, 20.5 hwy 72 miles per hour, and about 13.5 pulling a 8900# load (trailer). So far no joy but believe there are some issues that need to be addressed.
A diesel would struggle to get 13.5 mpg while pulling a 8,900lb travel trailer. I tow a 25' 6,000lb boat and I also have an 8,000lb+ 32' travel trailer. I can get about 12mpg towing the boat with my '07 Expedition (6 speed/3.73 gears) but it's more like 7-9mpg with the travel trailer. I wouldn't expect an Ecoboost to do much better, and possibly worse considering the fact it has more hp/torque which requires fuel to produce.
I agree on the Yukon/Suburban, I had one and the 5.3 is gutless and the 4 speed trans anyway is junk (had mine rebuilt at 47k miles). Not that Ford's 5.4 is a powerhouse, but it has a lot more torque at lower rpm.

I've watched you and "dieselone" spar for some time and truly have an interest in knowing what you may have learned over the past year. While I have a relatively new 2012 F150 Supercrew and am experiencing some break-in issues I believe all can be resolved over time. You can review all my feedback somewhere between forums #198 thru# 203. Refinement and checks and balances during the assembly process and verification at end of line at B&A would help customer satisfaction. I too believe the investment in the Eco-boost far off sets the diesel platform if the sole interest is pulling something under 11000#.
Any feedback for trouble shooting the system would be value add.Thx!

I would be pleasantly surprise if you got 20.5 on the hwy 72 mph.
Or 13.5 towing an 8900# camper at most any speed. A flat bed trailer, at 60ish mph might do it.
We do a lot of camping, and fuel mileage often becomes the topic around campfires.
Example: Josh normally towed his 32-35 ft "Tag Along" (not 5th wheel) camper w/sliders with a Ford 10V. I believe he said it is a Van. Usually averaged 8-9 mpg.
For this particular trip he borrowed a F-250 Diesel a couple of years old.
Said he was disappointed in the fuel mileage of towing at 60 mph. 12+ mpg.
Most Diesel owners I've talked with say that 12-15 mpg is about right for a large "tag Along" . And that 5th wheels don't do as well.
Haven't talked to anyone yet with an F-150 Eco Boost, so your input would be helpful. If you do get that 12+ mpg towing a large camper, it would be great, as gasoline is so much cheaper than diesel. At least it is around here.

We camp and boat a lot and talk to many different people as well. Our camper sits on a seasonal campsite so I generally see the same people during camping/boating season. We have about 4 people with ecoboosts and so far they're happy. Though they claim towing mpg isn't much or any better than the v8 trucks that had previously, but they love the towing power.
I really like the f150 but honestly I don't know if I'd pull the trigger on the EB. I'm at 112k on my '07 Expedition and I'd like to get another year out it. Then I'll decide on a Ram hemi/8speed, F150, the new GM trucks, or maybe even a new Suburban depending on the redesign. That or I'll just find a low mileage used Expedition EL.
I have nothing against the Ecoboost. I've driven a few and they are indeed impressive. Gas mileage appears to be a bit better than my Expedition while also having a lot more power. That's a win/win to me. That said, I'm not sold on Fords ability to avoid major issues. The spark plug debacle with the 3v 5.4 cost me $1,000 due to the plugs breaking off in the head.
But with as many Ecoboosts that have sold, there seems to be far more happy owners than unhappy. So we'll see. I think many have an unrealistic expectations of FE.
As for towing mileage, yeah, what you've found is pretty much what I've experienced. The 5th wheels are far heavier than a "tag along". I"ve only towed our travel trailer once. About 150 miles from the dealer to the campground. It's 32' with two slides and 35' overall. It weights around 7,500lbs empty. I towed it with my Expedition at 50-60mph and got about 8 mpg. No way will a current gas truck yield 13mpg pulling a camper of that size. We used to have a 25' camper and still never got more than 8-9mpg towing it with a '00 Suburban.
As for the Ecoboost, a guy that camps next to me has an '11 F150 Crew Lariat 4x4 3.73 ecoboost. Towing his 26' deck boat (about 7,000lbs) he claims he gets about 9 mpg at 70 mph. He says non towing mileage at 70 is 19-20 and 65 and under it's over 20mpg.

I'll leave it to the developers and calibrators to respond but there is an event associated with water slugging that occurs from the turbos that manifest itself as the engine lugging. This will also cause your transmission to downshift under load and thus not perform as anticipated. I'm told it some of the warmer states (i.e. California, Florida) where people are driving turbos (not just the Eco-boost) on the expressway and then slow to go through a toll booth, they experience the same thing under acceleration. This phenominom is characteristic of turbo enhanced engines and may be what your experiencing.

I have a 2012 Platinum with the Ecoboost w Max trailer tow and expect it to deliver 16 cty/21hwy empty. Towing 13/13.5 mpg with a payload of 9000#. While the 5.0 will pull adequately, you may experience some transmission shift scheduling under load and the fuel economy will probably be around 14.4 cty/17.8/19.0 hwy. Under load depending on your payload you may only see 10/12 mpg. Recognize if you order the maximum trailer tow they will currently demand the 373 axle ratio which is an ordering requirement. Two things to think about (1) the HID lamps are extremely expensive to replace should one fail. Also (2) the max trailer tow includes the 250 heavy duty mirrors which WILL NOT allow you to drive through a 9ft garage door opening without always having to tip the mirrors in. In full open position even with the mirror in the retracted state, you'll need about 9"-3" to adequately drive through the bay without hitting the mirrors.
I keep mine slightly tipped in all the time just to allow for clearance. Adjusting them continuously will not only frustrate you but eventually wear out the interface as the mirrors are only held in position by the plastic interface.

How many miles do you have on your rig? I experienced the same up to 4000 miles then found a major shift in both city and highway mileage. If I did not know any better, it actually sounded like you were sound you were driving my truck.
I experienced the EXACT SAME thing!!
There is as strategic method to fully mapping the processor that might help to fill the fuel tables which might benefit you.

Best part of the story...... I have a 5.3 Yukon, 6 spd trans. 2009. Great all around ride and mpg BUT GM saw fit to offer two different trail tow options. (1) call trailer tow, which provides the right engine, trans, and axle. and (2) one that includes the an increased radiator core and transmission cooler. Without both, you can only pull 5900# ,with both it's rated at 7900#. While it may be lame this rig can handle 8000# fine but watch the transmission temp. Failure to do so and overheat conditions can lunch the transmission at about $4200. dollars a copy. Oh the 5.3 will pull 8000# lbs so long as you don't exceed 67 mph. and labor doing it getting 9/9.5 mpg.
The reason I purchased the Eco boost F150 crew was that many I spoke to during our recent 2012 camping pulling travel trailers up to 9000# were looking at 12/13.5 with the Eco boost platform, while the Duramax, 6.7 Ford, and other big blocks were lucky to see 10.5 mpg. with the same payload. Sure I love diesels, but could not justify the MPG nor maintenance costs.
