My plane gets 8mpg and is an eco-disaster by any measure. That "Eco-boost" branding should be tossed out.

Pre-takeoff checklist
I have a 2016 F150 3.5L EcoBoost, 3.31, 36 gal tank, crew cab, Platinum - and it is a pulling machine! I love driving it unloaded or loaded, and when it's loaded, it pulls like a dream. Yes, the mileage drops with a parachute attached to the hitch, but that's to be expected. 68K miles and does not burn a drop of oil. For those who are visual - it's midnight black on black leather interior and all LEDs and we call her Elvira.
As for mods - I have none because I read the impacts of leveling kits and goober tires, so I keep it stock for the performance and I am not disappointed.
The only downside is apparently, my windshield is a rock magnet
I've spent $2k on windshields (higher deductible, don't go there).

I’m not looking forward to it if I ever have to get mine replaced.

I have an EcoBoost Flex. You can have Eco, or you can have Boost, but you cannot have both at the same time. It's fun to accelerate hard. It's also spendy.

Go up and see it in person. You’re in NC, correct? It’s not that far.

Just figured I'd add a little of my experience to the thread. I have a 2016 F150 XLT 3.5l EcoBoost with the 3.31 rear end and tow a 20' fiberglass walleye boat that is probably around 4500-5000#. It tows absolutely wonderfully, no problem with big hills or getting up to speed, I get about 12mpg towing it and around 18-19 unloaded on the freeway at 75. I have 130k miles on it now and have had exactly 0 issues with it other than a recall or 2 that were completed in 1 day without having to leave it at the dealership. I've also pulled my MIL's 28' camper around with it and get around 9-10mpg but it tows it without any issue at all. I even found myself at 80mph going up a huge hill not paying attention. The EcoBoost just pulls and does so at a nice low RPM.

What’s the payload on your truck? Sure it might pull that kind of stuff fine, but are you legal doing it

Don't have the numbers with me at the moment, but I've looked at it before and I was legal even with all the stuff I had in the truck.

My payload is 1776 lbs ('17 F150, 3.5L, Max tow package). A 4500-5000 lb boat w/ trailer would have a tongue weight of maybe 500 lbs (probably less, boat trailers are notoriously poorly balanced and light on the tongue), leaving plenty of remaining payload.
Photos of the camper/boat mine has legally towed all over the country, generally at 75 mph (weight distributing hitch used w/ the camper):

If the 3.5L EB makes 375HP and we use the widely accepted average of 3% loss of HP per 1000' with naturally aspirated engines, you'd have to be operating at close to 10,000' to experience a 100HP loss. Unless you're towing up Pikes Peak, you'll probably be OK the vast majority of the time with a 5.0L. Having said that, I'm saving my pennies for the 3.5L Powerboost as I'd LOVE to have the onboard generator to run our travel trailer, instead of carrying a stand alone generator.

I’ll buy that, but I don’t think max tow was available with a 3.31 rear end. Some of the 3.31 rear end F150s I looked at had hilariously low payloads. To the point of once you people a couple people and a few things in the back, pulling a trailer would be come an issue in terms of tongue weight. It’s something a lot of people never do the math on, to be honest.
Thats how I ended up with a F250 with the 7.3L. Occasional towing, I don’t need the diesel that’a going to be an emissions nightmare.

yeah, a lot of that is option dependent. You start looking at a loaded crew cab short bed, and they run out of payload fast with the 3.31

The average elevation of the state of Colorado is 6,800 ft. Your math above is forgetting about temperature, and just assuming standard temperature, but that isn't how summer typically works. On an 85 degree day (pretty reasonable), you'd tack on about another 2050 ft to that. So now your Colorado average is up to 8,050 ft density altitude. Using your 3% per 1000 ft, the Coyote would be down to 76% power available, best case, using an average altitude on a typical summer day in Colorado.
A 2022 3.5L Ecoboost makes 400 HP and & 500LB of torque. In the above scenario, all that 400 HP and 500 LB of torque will be available.
A 2022 5.0L Coyote makes 400 HP & 410LB of torque. In the above scenario, it'd be down to 304 HP, 96 HP less than the 3.5L Ecoboost.
Throw a Colorado grade that has you running at 100% WOT (common while pulling a camper up the mountains), and the Ecoboost truck will literally be running away from the Coyote truck pulling the same load. Within moments, the Coyote driver would no longer see the Ecoboost driver.
This is a very realistic scenario for anyone looking to buy a truck to pull a camper out west to do a little traveling.

Looked it up this weekend. I have 2050lbs payload on my XLT supercrew with 3.31 and 3.5 ecoboost 4x4. The 7000# GVWR is an upgrade though with the 3.31 electonic lock rr axle

That’s not bad then. Probably best case scenario for a 3.31 F150. Ford loves to advertise what their trucks are theoretically capable of pulling (and don’t get me started on that, it’s dumb to be pulling 10K+ on a half ton truck), but they never mention you have to have the payload numbers for the tongue weight.
bfmetcalf
Pre-takeoff checklist
I agree, I'd never pull a 10k trailer far, maybe some back roads for a few miles across town or something. It does pull and stop really well though, I want to say my MIL's trailer is in the 7k lb range and the truck has absolutely no issues pulling or stopping it.
2WD and lightly optioned?
Mine has 1508 payload that ends up being the limiting factor once you add 36gals of gas and a couple of people. I end up with ~900lbs useable.
bfmetcalf
Pre-takeoff checklist
Optioned pretty well and 4x4. It's actually one of the higher optioned XLTs you could get when I bought it. I've only got the 23 gallon fuel tank though. It's in the options that I gained too. The towing package, rear end locker and GVWR increase is where I got my good payload. There is also a Max Tow option and the even better Max Payload option, the unicorn is having both of those in combination.
Interesting. My KR FX4 has the 3.73 e-locker, trailer tow, and 7000lb GVWR. There’s not 500lbs in 13 gallons of gas so I wonder if the interior trim, all the sensors and tech, and 20” wheels make the difference. I know the 5.0 and the 3.5EB are close to each other in weight.
Mine’s a 2017, what year is your?
bfmetcalf
Pre-takeoff checklist
I'm not sure exactly what the difference would be. I'm sure there is some added weight with the king ranch package, but I wouldn't expect that much. I know they didn't offer the max tow or max payload with 20" rims in the past, not sure about newer ones. Mine is a 2016

Probably just the wheel size and transmission. The 2018+ has the 10speed transmission (co-developed with GM) which likely gets a bump in the "payload/tow rating"

The 2017 3.5L Ecoboost was the first F150 to get the 10R80 (mine has it). In later years, they brought it to the 2.7L Ecoboost & the Coyote.

Interesting, I swore the Expedition/F-150 got it in 2018 with the redesign.
jesse
Touchdown! Greaser!
2017 was a pretty big redesign year for the F150. It was the first year of the gen 2 3.5 Ecoboost, and the gen 2 came with the 10R80. The 10R80 has been great. The ecoboost has done everything I've asked it to do, and a lot more.
That said, it is going into the Ford dealer next week for new cam phasers/timing chain/guides/VCTs/water pump/etc. It seems Ford still can't figure out how to make a damn cam phaser last. Luckily it isn't costing me anything, it started acting up just in the nick of time. I am getting it fixed on the 20th, and my ESP plan expires on the 22nd. Truck has 90,000 miles with a third of that towing right up near 10,000 lbs, usually in the mountains out west.
I guess the 2.7L Ecoboost hasn't had the cam phaser issues. Ford updated the phaser parts in the later year G2 3.5 engines. We'll see how long mine lasts with the upgraded parts. I'm expecting to run this truck at least another 5 years. Maybe another 10.

I never heard a peep from the cam phasers/timing chain guides in my '08 F-150 which I sold with over 160K miles on the 5.4L. Only "repair" I ever really had done on it was broken passenger exhaust studs where were an annoyance rather than any problem with function. They still had the 4-speed auto transmission at that point, but it worked well and never skipped a beat.
jesse
Touchdown! Greaser!
My previous F150 was a 2001 with the 5.4L. I sold it somewhere around 200k miles. At some point or another, I replaced everything that was driven by a belt or related to a belt. Other than that (typical), I did have it blow a spark plug out of a cylinder once in a drive-through parking lot. Destroyed the COP that was attached to it. Had to heli-coil new threads in.
bfmetcalf
Pre-takeoff checklist
I had an '04 with the 5.4L before my current 2016. It made it to 235k miles before I had to replace the phasers, also changed the spark plugs and didn't have a single one break. My '16 has 128k miles on it and hasn't had a single issue (knock on wood)
For those that are even thinking of reducing tongue weight to stay "Legal" on their GVR, don't do it. A gusty cross wind or passing truck can give you a ride like Richard Petty gave you a bumper tap to pass.
That will get you to the scene of the accident, which is what you want to avoid.
Over GVR, and have an accident? It will most likely be less severe than the hitch weight one, and if it is severe, they will have an impossible task proving that you were over weight. I have seen a trailer go into oscillations at 60+ MPH in front of me, jack knife, and leave the highway. The leverage and velocity broke the hitch, and safety chains, the truck went off the right side, and the trailer went off the left side. Speed limit was 55, I was driving 55, he was in a hurry. I went through just after they parted company, and did not stop, as the traffic was heavy. People behind me had a better chance of stopping without getting hit.
I have driven with a boat trailer when the tongue weight was low enough that the seller lifted the hitch onto my ball, without grunting. I drove all the way home at less than 30 MPH, as that is where sway started if a car passed me. All the way home on back roads. I had a welder move the bow winch tower 2 feet forward to get good weight.

Reaching down and tapping the trailer brake controller will usually kill the oscillations enough to get it slowed down. I'd hope that people would just adjust the tongue weight so that it falls in the acceptable range for both payload and towed vehicle. Many trailers have the ability to move the axles forward or backward to help with adjusting tongue weight.
