ordering our next TV - 2011 F150 EcoBoost

were 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 145WB, 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.

were about to pull the trigger on ordering a new 2011 F150 Lariat Supercab 4x4 145WB, 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 Fords specs, and without the benefit of having previously been to a CAT Scale, Id 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, whats 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.

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.)
