TFL Truck hill towing contest: 5.0L vs 3.5L EB
Not exactly apples to apples, but (spoiler) the 5.0L wins gas mileage and less braking applications.

Gasp! Braking applications!?
I still haven't figured out why TFL has put so much weight on the brake applications. A quick stab at the brakes here and there doesnt mean they are going to melt and you are going to hurdle off a cliff into a ravine. I can't think of one test on any truck where they ever felt concerned or like there was an issue, including multiple tests where they have pulled 11,000+ lbs upand down the ike with an ecoboost
I'll still take a 3.5L that casually churns away at no more than 3500 RPM every time. Load up a 5Star towing tune and its like i dont even have weight behind me.
Also, the 10 speed is the great equalizer. Its not 1999 and we are not driving 4 speed autos anymore which had gear spacing to large to allow for a downshift or upshift. You can pretty much have any axle ratio you want and the 10 speed will even things out. The 5.0 was at little to no disadvantage by having the 3.15's.
Here is a gear ratio calculator I built if anyone wants to compare.

the 3.5 only sounds "casual". a quick look into the boost gauge and cylinder temps show a run away disaster in the works.
That said, its probably the better heavy towing motor. 470lbs of torque at a low rpm is awesome

And if the things you say were true, there are failsafes in the tune to prevent it from being a "disaster", as evidenced by the literally millions of ecoboosts on the road that are used to tow all the time.

And Mr. Truck's opinion should have little weight. I barely know what he is talking about half the time. He said in this video that the 5.0 was the same one from the early 90's and that it had been around for a long time. LOL.

I stopped watching TFL Truck videos some time ago.
Those goons just regurgitate the info that the manufacturer gives them, and none of their tests are very scientific. Those two F150’s were set up totally apples to oranges. I agree with what was said earlier, Mr Truck is completely misinformed. I cringe watching him speak.
If you want to compare 5.0 to 3.5 Eco, then you have to test 2 IDENTICAL trucks where the only difference is the engine. This means they should both be 4x4 or 2wd, should have same final get ratio, and have the exact same trim options. They should have the same wheel and tire package, and be aired up to the same psi. This isn’t always possible I’m sure since you may or may not be able to get option A with engine choice Y within trim package X, but you have to at least try to match them up. These guys didn’t even attempt to do a “controlled” experiment. By experiment, I mean comparison.

I'm happy with my 3.5 with a stock tune and I have run the Ike Gauntlet multiple times with it and plan to several times per year in the future. It's on the way to our favorite camping spot.
Honestly, I do miss the engine braking I had on my previous Tundra with a 5.7 liter V8. More displacement means better engine braking, that is not a mystery, it's just math.
As to Mr. Trucks comment on the 5.0l/302 Cu In motor, Ford has used this size for decades, not necessarily in the current Coyote config, but I understood what he said. The 302/5.0L in all of it's various forms is an engine with a proven track record for performance and development.
I have what I have, not gonna look to change out based on this video.
Most disturbing is that they are not doing an apples to apples comparison.
To be an accurate comparison it should be same rear end, trim package, features etc. As a comparison test (from a testing stand point) it's bogus.

These guys don't sway my perspectives about towing heavy, until they load up a travel trailer and stop trying to tow with mediocre trim levels.
Using a loaded truck for a max towing test doesn't tells me too much about how the best towing configurated truck tows.
I would love for them to test a HDPP against all half tons, including the 3/4 ton towing a travel trailer.
