I have my F150 back, I wanted to wrap up this thread and my wife wasn't home so I ran some acceleration tests with the trailer to compare the 3.5 Ecoboost with the F250 and diesel combination.
I will go ahead and confess that the diesel will outrun the 3.5 Ecoboost, at least at speed.
I made three runs up the same hill as I did with the diesel.
The first was a little slow off the line but I was concerned about breaking the tires loose and was a little reserved getting on the gas.
The second I threw caution to the wind and just stomped the go pedal. There was a little tire slip and it didn't feel as strong as expected but I matched the launch of the diesel (which I complained about earlier). This probably best represents an ordinary keep up with traffic launch capability.
The third I used to 4wd to be sure that I used the full capability of the Ecoboost. I did this partly just to see what the engine can do but can justify using 4wd in the F150 and not the F250 because the F150 has automatic 4wd that can be used somewhat safely on pavement. Plus, the F250 never spun its wheels anyway.
The variations in the runs seemed in line with the adjustments that I described so I felt no need to waste my time and further abuse my truck by repeating the tests.
Bottom line, the Ecoboost held its own up to 20mph then started dropping off. The maximum speed in test strip was 10mph slower than the diesel. To me it is more than adequate for this size of trailer and the driving that I am doing with it. The F150 is adequate up to its rated capacity and probably performs better at rated capacity than an F350 does at its rated capacity. The 2019 model should outperform my 2016 model. I can understand why people regularly pulling trailers over 12,000lbs would want the diesel.
