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.

I'll keep you posted. I'm tried and Blue Ford (41yrs) but frankly have to admit I've researched many different power trains. Currently I own have a 5.3 6spd Yukon XL we love 15.8/16.4 cty -19.7/20.0 hwy; the F150 Eco boost crew is still out for vote but will be towing a 8200# trailer with slides in the 2013 season.....
Stay tuned!!

While the Eco boost boast some good fuel economy exceeding 67 mph will start to show significant decline. Optimum fuel economy will net pretty much what he has stated but pulling a 7000# boat at 70 defeats getting good MPG. You over the peak torque curve, especially if he's got the 373 axle.

Stay tuned: While were into the first season of putting the Eco boost to the test, I assure you there will be additional threads to provide accurate feedback regarding the Eco Boost's capabilities including the MPG loaded and unloaded.
The goal is to find what rig will adequately pull a 8,000/ 10.000 lb trailer without breaking the bank or spending a fortune in fuel and oil changes.
Due to the spring rates and overall vehicle design towing a fifth wheel may not a good decision, but for the average tow behind... "Campers here we come!"
