So I have a 2017 F150 with 3.5 Ecoboost and 3.55 gears. I rented a 6x10 dual axle dump trailer and loaded it with 2.5 yards of landscape rock. I'm thinking maybe 8000-9000lbs total.

Engine did the job, but felt like a lawn mower. My previous 6.2 V8's easily outperform this motor. Now I know why this motor can't be placed in a Super Duty.Trailer also pushed the truck around and was tough on the brakes. Thankfully only went about 8 miles.

This motor is great for anything 5000lbs or less, as long as you are fairly aerodynamic. My truck gets 7 mpg towing an ultralight Passport 153ML.

Since I drive most miles empty, I like this truck and it is a good compromise. If I pulled over 5000lbs and used the truck only as a tow vehicle, I would pass.

7 mpg is about what my 2007 Hemi gets pulling a very similar RV (the one in my signature pic, it's 17' and 3500#). I get around 8 mpg. It's not necessarily the weight but the wind drag.

That's quite a bit lower mpg than other EcoBoost owners report, even when pulling heavier loads. [emoticon]

I pull 8k all day up and down grades and never felt this engine lacked for power. And I came from an 8.1 with a 4.10. Acceleration on short on-ramps is not an issue. I typically get 9-9.5 depending on terrain. The 3.5 does not have that nice deep roar of the 8.1 ; )

I can understand feeling pushed around with that rig. Knowing I was towing 8k I opted for Max Payload and have the heavier suspension and 3.73.

Oh, and you can find the 3.5 de-rated in the Transit 250 and 350.

I suppose different drivers and different impressions.

Take it easy,

The local Ohio boys used to do a trailer pull up some steep hill and the F150 Ecoboost outperformed the V10,7.3PSD, and maybe some of the 6.0PSD.

I think the description of a lawn mower is a bit of a stretch unless something was wrong with it.

I thought the 3.5 Ecoboost is a V6?

I drive a 2015 Explorer with the non turbo 3.5 liter V6. From that experience I would say that the 3.5 Ford V6, does need the turbo.

But, on the other hand, given how others with the turbo 3.5 liter V6 wax eloquent about the power of the turbo, it does seem like there maybe something wrong with the OP's turbo V6...unless of course he happens to be Big Daddy, Don..the Swamp Rat..Garlits.

Are you absolutely sure that you have the 3.5 Ecoboost and not the wimpy 3.5 with no turbo?

I don’t doubt the mileage drop to 7. We had a GMC with a 350 that got maybe 14 mpg empty. Towing I’m not sure it hit 5. Depending on the terrain we couldn’t make it 300 kilometres on a tank. Towing with a gasser has a big effect on range. Our power stroke was much less impacted but it was kinda loud. Good truck though. The GMC was junk.
