100% agree.

of coarse if you hit rough water you might feel different

 

I read this earlier today and thought it was pretty accurate. It's one of the most even head to head tests that has been done on the two engines. Most of the time they have one 2WD and one 4WD or different axle ratios or something else to skew the results. The test was apples to apples.

Yeah the heavy duty trucks aren't nearly as comfortable or sporty. They really shine when it comes to pulling a gooseneck though or hauling weight in the bed.

Get the right balance and dont load unnecessary cargo into the F150 and I bet it will work a lot better for the OP all around.

The 6.2 f250 isn't exactly a slug but it shifts and performs like a work truck, not very engaging to drive and rides pretty rough.

 

2015 super crew, 3.5eco, 6.5 bed, 4x4.

My toy hauler is 7500 lbs dry, tall and pushing 10k loaded. I cruise up the Cajon Pass (6% grade for 5 miles) with easy. 65MPH @ about 3500rpm all the way up. If I put my foot in it it will shift down and pick up speed. I get 8mpg towing and 17.2 mixed daily driving.

My previous truck with the 5.4 could barley pull it at 35MPH and fricken screaming with a hot tranny.

The EB is a towing beast. I considered a Diesel and glad I didn't got that more expensive route.

 

Info in this thread is one of the reasons I read this forum, so thanks.

Can we please hear a bit more regarding different transmissions, diffs, brakes, springs, etc. with the 3.5 and 5.0, and the various tow packages? This type of information is almost impossible to get from the dealer and will weigh heavily in my decision of which motor to get.

 

There is only one transmission - the 6R80 is used in all F-150's. The new 10 speed will start showing up next year.

This should help:

I haven't read any comparison on the engine braking with a load descending a hill. The 5.0 does pretty fair, but I think my 5.4 had a little more hold back, but the brains in the transmission on tow/haul are pretty cool.

Any comments on the downhill compression of the 3.5?

 

The 3.5 does OK in this area and will help keep the truck's speed in check but that is one of the very few areas I will give the 5.0 the advantage. It is 1.5L bigger with a higher compression ratio. No matter how you slice it the engine braking on the 5.0 will be better. However, with a big trailer on a long hill you will be using the brakes with either engine.

 

I can only compare my 2010 5.4 to my 2014 Eco since they have both pulled the same trailer. I would give the engine braking advantage to the 5.4. Based on the larger displacement, I can't see the eco being any better when compared against the 5.0.

It does work in the Eco enough to satisfy my needs. for comparison, I'm talking about a 6-7k trailer (depending on the toys inside) and decending down 8% grades lasting over 10 miles. Brakes required on both trucks. My F350 was a different case though....

 

FWIW, I had a 2013 5.0 Platinum SCREW 4x4. My 2016 KR (same set up)with the 3.5tt has WAAAAY more torque and if you want the maximum towing package (12000lbs) you have to upgrade to the 3.5tt. That's Ford saying the 3.5tt is a stronger towing platform. At 420lbs. of torque I can definitely see why. I was looking for the 5.0 (just a hardcore V8 guy I guess) but had to take the 3.5tt as the KR I liked had the max trailer tow package. Boy was I surprised at how quick the 3.5tt is off the line (gobs of torque) but I really like the turbo whine as well. I can also really tell this truck is lighter than my 2013 Platinum was, it's just easier to "flick around" than the Plat was, feels much less "ponderous" and lethargic...I think its both the added torque of the 3.5tt and serious weight reduction that is making the diff. Shame of it is I rarely tow anything but am ready if need be.

 

7500 pounds dry? Judging from the picture, that's about a 21-23 footer, right?

I think you may want to check your actual dry weight. My guess would be about 4 to 5 k depending on whether or not it has a slide out.

I have a 31' Jayco TT with a slideout that weighs in just over 6k dry. I figure loaded I'm just shy of 7k.

I could be wrong, it has happened , it's just that your trailer doesn't look large enough to have a dry weight that high.

For those interested, my 2016 SCab 5.0 w/3.31 gears pulls it just fine! I get just over 10 mpgs while towing and average 18 mpgs in my 65 city / 35 hwy driving. On trips I have gotten 23 mpgs at 79 mph on the interstate.

Don't expect 6th gear while towing this much weight though... if it happens to get there, it ain't staying! Keep in mind though that 5th and 6th gear are both over drives. I usually turn 6th gear off when I tow my TT.

 

I don't see how you can get 35 mpg highway. Even keeping it at 55-65, unloaded.

Granted yours is a scab and mine is a screw with 6.5' bed, so heavier, but the best I have ever gotten was 24.5, and that was in the winter time (no air conditioner running) and empty. 5.0 with the 3.31 gear too.

I did get really great mileage (22.7) on a 1600+ mile drive to DC and back in the winter too, loaded pretty good and hauling me, wife and kid

But 35 seems crazy

 

Sorry for the confusion... I drive 65% in the city and 35% on the highway. I WISH I got 35 mpg's! Maybe it would have helped if I had included the % sign.

Is there an embarrased emoticon on here?

 

Ok, that makes more sense...

 

I've got a 2015 5.0 V8 and constistantly get 20.5-21.5 mpg when not towing. Very satisfied with that. My old 2003 5.0 Silverado was around 16 mpg. They've made lots of improvments that way.

My mileage drops when I tow my cargo conversion but I know that it's because of wind resistance as other (low profile) tow items have almost no effect on gas mileage.
