3.5 or 5.0. trying to decide

Thinking of replacing our explorer with F150 to get more room as family grows. I would add a bed cover or topper for luggage on vacations (hey Ford, where's the expy w/ 3.5???). Sorry, that discussion is for another fourm.

Take 2 identical supercrew, 4x4, 3.55. The only difference is the engine. My normal everyday to work and back mpg should be real close. So close it would take a long time to justify the added cost of the 3.5.
Now, add a 5000 lb boat to the back of it. The extra torque of the 3.5 will come into play. Now this is my thinking, the 3.5 will have fewer downshifts, more turbo boost = less mpg. The 5.0 will probably downshift more so you have higher rpm = less mpg. I'm wondering how much mpg difference, if any, between the 2 motors with the load.
Is this a good question? Or am I opening a thread that could go too many different ways?

We are in central Missouri. County roads are slightly hilly. The explorer pulls the boat around with no problem so the F150 would hardly know it's there.

Has anyone seen a side by side comparo of the 2 motors the way I explained above?

Thanks in advance for replys.

An F-150 with the 5.0L and 3.55's will get you about 9600 lbs of towing ability. The EB will get a little more. The EB is only $750 more than a 5.0L so that's not a real argument.

To be honest, a 3.7L F-150 will tow a 5000 lb boat easily enough.

Kinda of subject.
I am looking at a F-150 with the ECO BOOST

My trailer is a PJ 83” x 22’ Heavy Carhauler With 6” Channel Frame, 6” Channel Tongue, 7000 lb axles, brakes, 2’ Dovetail w/ Stand Up Ramps (31” x 66”), 10K drop jack, Crossmembers on 16” Centers, Removable Treadplate Fenders

Will the Eco/f150 pull it fine safety? Then adding in a 3500lb-4200lb compact tractor and someday a Bobcat that will weigh in around 8200 Lbs.
Or DO i need the 6.7 in a F-250/F-350

This will also be a daily driver in the winter for the wife and a family travel vehicle
Sorry for the long post but i am not sure.

So you're saying that a Bobcat and the trailer will weigh around 8200 lbs? If so, a properly equipped F-150 will be just fine.

capn kirk is gaining momentum as a positive member of FTE.
When it comes time to pull 10k lbs every day for work you'll find that the 150 is capable but super duty is the truck that is ment for that purpose. Love my ecoboost and happy with my switch from 250 to 150 but remember its a half ton truck diesel superduty will do the bobcat pulling better and safer. And you need to check the weight of that trailer and gear you'll have with this machine could easily go over 150s 11000lb capacity a problem with your insurance if you crash while working

The wife and I just sold our F350 6.7 4x4 and our 5th wheel camper. We could have any light truck we wanted but wanted the 3.5 EcoBoost after looking at the specs. Because the 6.7 uses a similar turbo charger, I wasn't afraid of it and it's reliability. Also, the low end torque is great. Ford has done a great job of late in engine design and reliability. We got 19.4 avg mpg @70 mph on the way home from the dealer.

The engine is smooth, has V8 power and is very well built. We couldn't be happier.
