Towing with 3.5 eco boost

[wapitibob]

I have the exact specs of the op vehicle but a 2020 and the tow rating is 11,300. GVWR is 7050. The 2025 has a max tow rear axle option.

There's a formula out there about derating your towing capacity for altitude, temp, weight , etc. you get the idea. usually about 30 percent. depending on where your driving. Flat Midwest at 70 degrees or over 110 degrees crawling western grades.
Like someone early in the post , it's the heat that gets them.

And keep in mind, it’s not usually the heat in the motor, it’s the heat in the transmission! Monitor your tow gauges to include trans temps. These newer 10 speed trannys generate a ton of heat! And because trucks are designed by bean counters and sold to soccer moms and dads, they are no longer equipped for real work and don’t have auxiliary trans coolers. They have heat exchangers that are often insufficient. I promise you, if you do a lot of off road hill climbing or slow speed towing (winding mountain roads) that will include lots of gear shifting with the torque converter unlocked, you are going to see shockingly high transmission temps. Keep a close eye on your gauges, and consider more frequent transmission fluid changes at a minimum.

I have a 6500lb 29' hitch to bumper trailer that I've towed with a expedition 3.5ecoboost (not far off the F150) and a 7.3l superduty.

Ecoboost 3.5 - has the power to tow it, turbo works hard pulling up moutains (ie silverthorn CO to eisenhower tunnel climb for example) and trans/engine heat climbs but it's doable. Was always up against payload rating. It gets thirsty. But the major aspect folks ignore when talking about "tow ratings" but in the context of campers isn't the weight but handling, you're towing a billboard that wind pushes around. That part there is a huge difference (even with good hitches) between 1/2T chassis and heavy duty chassis.

7.3L superduty - has the power. Spins 4k rpm to pulling up moutains (ie silverthorn CO to eisenhower tunnel climb for example). Trans/engine heat seems to maintain better than the ecoboost. Plenty of payload. It gets thirsty. Is MUCH more stable against the trailer being pushed around by wind.

I have a 2021 f150 with the same setup.. and I wouldn't wanna tow much more than my sxs with it. I found that it lacked power and fuel mileage was about 9-11 mpg. If your gonna tow something get a diesel. I got mine thinking it would be okay to tow with. It sucks

Yours must be broken if it feels underpowered towing a side by side.

That is what I was thinking.

Just got thru towing an enclosed trailer across the country. 9k pounds.
Pulls fine. But got about 6mpg going 75

And that’s a 23 3.5 eco
