No "group think" here, just the numbers....I have the 3.5 ecoboost in our 2018 Explorer and that motor has the power to tow, no question about it.
The fact is that most all trucks and tow vehicles will exceed their carry capacity with an RV before they reach their towing capacity. In p.meier's case, his brochure tongue weight of 880# is likely to be 1000# in the real world.
Newer 150/1500 trucks have so many configuration options that you need to go by the sticker on the door jamb for what you can carry in your specific truck. Best way to understand what you're towing is to take it to a scale, but hard to do that before you buy it.
That said, most forum posters that tow that class trailer with a 150 have no issues and are happy with how it tows.
