ordering our next TV - 2011 F150 EcoBoost

we’re currently pulling a 2002 25’ Safari SS, which weighs in dry at 4,800 pounds, 6,300 GVWR

with a 2008 F150 Lariat Supercab 4x4 145”WB, equipped with a 5.4L V8, and 3.73 non-limited slipgears - GVWR 7,200 / GCWR 15,000. it certainly performs adequately for us.

I suspect that any possible change to a bigger TT in the near future might get us up into the range of a late model 27FB which is rated 7,600 GVWR.

we’re about to pull the trigger on ordering a new 2011 F150 Lariat Supercab 4x4 145”WB, 3.5L EcoBoost, and probably with the 3.55 LS gears – GVWR 7,2000 / Payload 1,760 / Max loaded trailer weight rating 9,800 / GCWR 15,400.


having pored over Ford’s specs, and without the benefit of having previously been to a CAT Scale, I’d like to ask these questions –

among those of you who actually own or have actually driven the 2011 Ford F150 equipped with the EcoBoost V-6 Engine,

what drive axle ratio did you select or purchase - 3.31, 3.55, 3.73, 4.10 / limited slip, or not ??

what does your Ford documentation tell you about
the Payload Weight Rating, and

the Maximum Loaded Trailer Weight Rating, and

the GCWR
of your TV ??
and, what’s the GVWR of your TT ??

so, are you happy with the performance of your TV / TT combination, or, given the chance to change, would you pick a different F!50 drivetrain ??

what would you change, if anything ??

if gasoline and monthly payments were free, I'd just say the heck with it and order the 3.73s and the "Max trailer tow package", but, they're not....

thanks in advance for your input !!

best,

I'm looking at the Eco Boost also, and I'm not finding many tow reports on it. By most accounts the engine has plenty of power and torque. I think I'll wait till after summer and read the tow reports. There is plenty of interest in it on the RV net tow vehicle forum.

What I'd like to know is the engine RPM at 60 (or any speed) in top gear with the various axle ratios.

My inclination would be to get the maximum tow package w/ 3.73 doesn't that include heavier differential? Isn't the engine speed at cruise prettly low due to the 6 speed overdrive with any of the ratios? I've seen several reports of highway fuel economy over 20 mpg unloaded w/ 3.73.

I tend to keep the tow vehicles a long time. One other consideration for me is the standard F250 w/ the 6.2 V8. Advantages (to me) as old vehicle I think it would be easier to service and maintain. Disadvantages vs. eco boost: fuel economy. Prices are not that far apart.

RV.Net Open Roads Forum: My Ecoboost arrived today - and it's black

This guy tows a lot, and just got one. He has to run up the 1K miles for break in prior to towing. The Rockwood he tows is more challenging than our Safari 25s.

I am also concidering a new eco boost F150, am waiting to hear feedback from other owners. I would prefer the 6.2 but its not available in a super cab. The 3.73 with max tow package is the only way to go. For the small amount more in gas its worth it.

Got the Ecoboost last week. 3.73 with max tow. Averaging close to 17mpg at close to 80mph on freeway through mountains around Bozeman Mt. Averaged close to 19mph at 65mph freeway driving. No towing so far, only 500 miles on the rig.
This was according to onboard computer.

When you have a chance, can you get the rpm at cruise speed in top gear?

thanks

Get the max tow package and the hd payload package.
Your tongue weight is going to use up half your stated payload.
Add fuel passengers and gear and you will be at the max for the pickup.
I ordered a supercab with 8 foot box. Max tow and hd package.
Can tow 11,300 lb trailer and payload is 2670.
Hope I like mine when it comes in.

Also max tow will give you the 3.73 gears which is best for towing and really doesn't make that much difference in rpm.

hi, Greg,

congrats on the new TV -

is that a 4x2, or a 4x4 ??

thanks!

The turbo is an integral part of the drive train package, incorporated as part of the engine and can not be bypassed nor would one want to...

I think the question is really whether or not the engine will be under boost all the time while towing in the mountains.

With a 3.5L V6, I suspect that towing a trailer up a grade will always have the turbo generating positive pressure in the intake ("under boost" or "in the turbo"), but I have no special knowledge of the EcoBoost V6. (I'd like to, though... seems like a good package if I were buying a new truck this year.)

We had a 25' 06' Airstream with 08 Tahoe; little underpowered, so got a new 11 Tahoe' with 30 more horsepower and 6 speed. Not sure this was a good choice for new Airstream 25', but we will see.

Well, friend of mine just got his EcoBoost for pulling and he is raving about it. Check out these 2 video's if you have not seen yet. First video is impressive; but second video is ridiculous! I have new Tahoe 5.3 and will see about replacing with this new Ford!

1st- NASCAR 24 hour pulling max load 11,000 lbs, max speed!



2nd- max load pulling up hill, "flooring it" vs Chevy and Dodge...WOW!



More:
Last month, we told you about Ford’s three new powertrains for the 2011 Ford F-150. At the time, Ford announced the truck’s first implementation of its 3.5-liter EcoBoost V-6 but was mum on power ratings. Today, Ford said the engine is rated at 365 horsepower with 420 pounds-feet of torque on regular fuel.
Those torque ratings beat out all but the new 6.2-liter V-8, available on the top-of-the-line F-150 and base 2011 Ford F-Series Super Duty. The EcoBoost’s toque ratings are better than the 5.3-liter and 6.2-liter V-8s in the 2011 Chevrolet Silverado 1500, the 5.7-liter V-8 in the 2011 Ram 1500, the 5.7-liter V-8 in the 2011 Toyota Tundra and the 5.6-liter V-8 in the 2011 Nissan Titan.
Up to 90 percent of the EcoBoost’s peak torque will be available from 1,700 rpm to 5,000 rpm — intriguing figures, considering the 3.5-liter EcoBoost implemented on Ford’s cars and crossovers hits peak torque around 3,500 rpm.
The V-6 can tow 11,300 pounds, which is the same maximum towing figure as the 6.2-liter V-8 and beats the best ratings that Chevrolet, Dodge and Toyota can cook up right now. Maximum payload is rated at 3,060 pounds, again the best rating for a half-ton pickup.
The 3.5-liter EcoBoost V-6 will be mated to Ford’s revamped 6R80 six-speed automatic transmission, which is rated for up to 7,000 rpm. The model will also feature Ford’s electric power-assisted steering system, new to the Ford F-150 for 2011.
All of this is supposed to give the EcoBoost not only the best towing, torque and payload figures but also “outstanding” fuel economy, Ford says.
Ford has yet to release final gas mileage figures for this powertrain. The 2011 F-150 will be available later this year; the 2011 F-150 with EcoBoost will be available in early 2011.
  • Best-in-class 420 pounds-feet of torque at 2,500 rpm versus premium V-8 competitors
  • Up to 90 percent of peak torque available from 1,700 rpm to 5,000 rpm
  • Best-in-class 11,300 pounds maximum trailer towing versus all competitors
  • Best-in-class 3,060-pound payload rating versus all competitors

Any time your "foot" is into it, it is in boost. It's the way the turbo works.

hmm. that's about the same as I'm getting from my current TV....

hopefully, it will improve with age?

I was looking at ecoboost w/ maximum tow package. I stopped by to drive it today, but truck was out at the time.

With the 3.73 epa mileage is the same as the other ecoboost axle ratios, 22 mpg hwy 2WD model. I can see no reason to avoid the max tow package.

The 5.0 V8 is 21 mpg so I don't see buying it only for the fuel economy.


What appeals to me is the big helping of low RPM torque which comes on in the high teens of RPM. It should have pretty near full torque at stall speed of converter. Less downshifting on hills, more diesel like to drive.

nowhere have I ever been able to find a Ford F150 "EPA Mileage" table for a 4x4 SuperCab or SuperCrew vehicle, much less with 3.73 gears....

seriously, did I miss it?

you might find similar information in an independent publication, but it's not EPA....


I diagree that "With the 3.73 epa mileage is the same as the other ecoboost axle ratios"

it's virtually impossible that any two "same" modern vehicles, but for the final gear ratio, will achieve the same mpg. the engineering and physics don't work that way.


I'd have been thrilled with the EPA Mileage numbers that get bandied about so loosely, in any of the last 5 F150s we've owned.

too bad they don't really apply to my truck, or the new 2011 models we're all talking about here!

Its on the window sticker. Browse dealer sites where you can see the window sticker.

Re epa mileage, our experiences differ. At least here in so. CA with the mild weather, I've always met or beat the epa highway mileage at steady speeds of about 70 mph. I have had close to 20 hwy mpg out of my last two 2wd half tons, a 1992 Chevy 350 and 1997 Ford 4.6. I've seen some reports of 1800 rpm at 70 mph w/ ecoboost 3.73. With 3.5 liter, perhaps any advantage from even taller ratios is vanishingly low.
