Out of curiosity, why? Not being argumentative, just wondering��*
You think a 2.7L has 250K miles of trailer towing in it's life?
Well,,,, does a 2.7L have 250K miles in it's life regardless what it's moving?

How much of the time do you think the 2.7 would be on boost while towing? Would it live long operating like that?
When they want to replace engines every year. The only way for this to make sense is for the type of people who buy a heavy duty pickup to get groceries.
I regularly tow around 15k on a gas 6.2L. Up big hills or into a windy day (30+ MPH headwinds aren’t uncommon), it will run in fourth or fifth gear, at higher RPM. This is not a problem with the engine designed for doing that all day long. It also has the torque to move it; over and over and over...
I understand the rated numbers for the 2.7 Ecoboost aren’t crazy lower than the 6.2L, but you are also comparing drivetrain loss from the light duty F-150 stuff, which generally loses 15-20% on the way to the wheels. With the heavy duty parts of an F-250 or moreso, the F-350 (including dually), you lose as much as 30-40%.

I would imagine that it's not built any lighter than the 3.5L EcoBoost is, and they put a lot of miles on the original version of that that they did the test series on.I am not sure. Has any research been done to see? I can google it I guess*

If you are curious, google why Ford went to the larger displacement 7.3 gas engine for the heavier trucks. They certainly could have gone with a smaller engine and boosted the snot out of it, but they did not. The smaller boosted engines make much more sense in the F150 class of trucks and below.

Keep in mind weight is a huge factor in automotive design. Comparing a 2.7 eco boost to a heavy hauler is hard to do. 500 pounds of engine weight is a big number for a truck that is rated at 7000 lbs vs one rated t 80,000 lbs.
